Anyone here who had - has a Rodgers oil temp gauge installed and replaced it with the HD gauge (CVO silver)?
Wondering if the sender and wiring can be used and if it will drive the HD gauge.

Duane, do you mean the gauge that was offered by Roger (Rodger?) McEwan? That's the only other oil temp gauge I remember.
It was first released by him after a long wait and many promises. Promises that included being a "good visual match." Trouble was it wasn't. Not very close at all actually. Of the few he got out in the field I kept track of four that failed also. Not too long after the phones stopped being answered and the business closed.

Forgot the name, yes the McEwan gauge.
Mine works OK, just constantly fogs up. Since the knucklehead no longer is around I have considered replacing it with the almost made to match HD version, just wondering if I can use my McEwan sending unit and it's current placement with the HD gauge.
Don, also have to q's in the twin cam section if you care to take a gander and reply.

Where is your sending unit currently mounted Duane? And what size pipe thread is it?
The fitting supplied with the HD gauge is 1/8. Sending units might be the same; and might not. If yours is a major pain in the ass to change you're not going to hurt anything by trying it. If it's accurate; great. If not, change it at your next oil change.

Just looked at each. Hope any of that was helpful :2vrolijk_21: .

In the pan just below the cat, it is the sending unit supplied with McEwans gauge.

That being so make the whole thing an easy choice. Wait to change gauge for whenever the next oil change is necessary. Then pop the fairing and change the sending unit at the same time so you neither ever have to worry about the accuracy nor waste the oil.
I've got a gauge sitting here for the Road Glide. It'll keep right on setting until whenever the bike needs an oil change. The red bike's little engine glitch notwithstanding I really try hard not to do things twice 8) .

Well, this certainly isn't at all encouraging. Rod put one of these in the green bike during the engine build.........and it is not at all a good match. Appears to be working fine tho'.....for now. We'll see how this goes, and if need be, it'll get replaced with whatever is available.
One thing I do like is it is right there in front of me. No more of this leaning over to the right, contorting my torso to press a button on a dipstick meter that only worked occasionally anyway...........and that had to be clamped in place so it wouldn't blow out. Really diggin' the oil fill spout that came with my Baker OD6..........and my Baker OD6. Makes a huge difference.

If I recall correctly, the McEwan sending unit is one wire where the HD unit is two wires.....
Easy enough to retrofit but not a direct replacement.

The McEwan sending unit is one wire. Can't speak to the HD unit.

It's separate leads for signal and ground.

Does the HD sending unit mount in the oil pan like the McEwan sending unit? If so, and should it become necessary, would it be feasible to retrofit by running the ground wire to frame from both the HD sending unit and HD gauge, thus saving the signal wire and the trouble of routing it again...........or would that be too dirty?

Henry, the spec sheets provided with the HD gauges do not put the sending unit in the pan. Instead placing it in any of several different locations on different year/model bikes. None of those locations are as effective or as easy as putting them in the pan. And that's what many here have done.
The HD spec sheet also has a much busier new harness than is necessary if you're replacing a pre-existing rain gauge. The new install specifies routing to the fuse panel for power, to the newly installed sending unit and on to the instrument in three legs off the supplied harness. Humbug.
At the existing gauge there's already power and ground for instrument and light. So all that is needed is the signal from the sending unit. You could take out the single wire sender, put in a two wire sender, use the signal wire and simply add a ground. Would work just fine.
You'll snip the terminal or socket (whichever it has) off the end of the old signal wire to use the two wire socket matching the new sending unit. Then just take its ground side to a good ground.

Thank you. :2vrolijk_21: I'm not thrilled with the look of the McEwan gauge and its cosmetic differences (I have straightened it since this picture was taken), but I'm not torn up about it either. More concerned about instrument failure at this point, especially since having run across this thread, and learning of McEwan's demise, and the accompanying lack of end user support. We'll see what happens with this thing, and if the need arises, I'll simply replace the sending unit and gauge and modify accordingly. :2vrolijk_21:

I understand. Had one of the McEwan instruments in hand when he first released them several years ago. Had spoken with him during work up to release and the piece wasn't the cosmetic match he'd promised it would be. Sent it back without ever fully opening the package. That was before several others suffered failures and McEwan's shop closed. So I simply lucked out.

I won't go into the details about how the dealer didn't follow my request to install mine according to the "Dead Cat" diagram. But needless to say, mine picks up the temperature after the oil has passed through the cooler. Don't be so quick to change yours out Henry. The HD unit I had added pre-delivery is constantly fogging up. Moisture builds up inside and fogs the lens. This does not happen on the other gauges, only the oil temp. Washing the bike, dramatic (+/- 15⁰) temperature changes, and coastal humidity will all cause it.
-
The only problem I have with the McEwan gauge is that it fogs up. Don't know why but every time I go for the first ride of the day the gauge fogs up for about an hour or so. Weather does not matter - does it all the time.
The gauge cosmetic difference is not enough to concern me, but I am considering ordering the HD gauge when our dealer has their 20% night and see how it works with the McEwan sender

Duane, I don't remember who. It's been quite awhile back too. But someone here wrote about attempting to use the sender packaged with the McEwan gauge with the HD branded gauge after their McEwan gauge had failed.
Searched but could not find it. Remember whomever it was saying the reported temps changed though. Whether the sending unit grounds through its own body or through a ground wire is of course irrelevant. But I'm sure I remember someone reporting that there was some noticable difference in the temps reported without swapping the sending units. Using the sending unit packaged with the HD gauge made that gauge report the same as the McEwan gauge had when used with it's own sending unit. But mixing the two didn't keep the numbers consistent.
At least I think that's what I remember being reported.

Harley gauges fogging up always makes me chuckle for some reason. It's a crap shoot which ones do and when they'll start. The red bike's fuel gauge never had; until last summer. The... well; some will, some won't. They do it just to mess with your head.
-
My McEwan gauge will fog up on initial start and stay that way for about 45 minutes or so. After all these years, I'm accustomed to gauge fog. Learned to live with it, I guess. This gauge is just another chapter in the continuing saga of the Ditch Pickle. Everything always works out for the better. We'll see how this one unfolds.
-
Henry doesn't it make you wonder "why" it always fogs up"?
When we were in Gatlinburg for the rally 2 years ago we had record temps 100+ and dry every day, yet the gauge still fogged up every morning. With the gauge lights always on on our bikes you know they should be dry.
Just doesn't make sense
-

Not a big deal Donny boy. I'll put the gauge in see how it works (or not) and if needed change the sensor at the next relevant oil change. And if it needs to be re-wired a bit - :nixweiss: won't be like it's the first time

I think the units are not hermetically sealed, therefore, moisture gets in there and clings to surfaces cooler than the inside of the unit. Not sure why. Seems the only solution would be to place unit in a drying chamber for a period of time and then seal every nook and cranny.
I'd rather ride. :2vrolijk_21: The fog dissipates shortly anyway.

I did an install of the guage just the other day and the instruction sheet now has them being installed into the pan, It even comes with a reducer bushing. HD finally woke up on this one. The guage part number did not have a new rev though. I will try to remember to post the new install sheet.

That made me laugh. Thanks for sharing that Jim. It's either sad or funny that it took the MoCo this long to recognize the obvious and the simple. So it might as well be funny.

Sorta makes one wonder why it took the MOCO so long to figger out why they put that second bung in the oil pan. :coolblue:
