Anybody having an issue with the HA90 blowing fuses?  I bought two of these, one for my ultra and one for my seeg.  After fussing with the install on my seeg for a couple hours and flowing several fuses, I swapped the unit for the second one I hadn't yet installed on my ultra.  No problems.  Worked fine for a month.  I sent the other one back to the MoCo.  

At Myrtle last week, the new unit blew a fuse after about an hour of playing.  Radio works fine, Hogtune speakers are outstanding.  Just no MP3.  I haven't had a chance to pull the fairing yet, problably do that tonite.  Getting a bit annoying.  I'm fairly certain that I have the wiring correct.

When the first one was blowing fuses, Instead of splicing into the one of the grounds going to the radio, I cut the wire and grounded it to the radio directly.  Seemd to work fine, until Myrtle.  Don't need two grounds?

Any help would be appreciated.

Now I'm sure that I "dont'" have this thing wired correctly.  Pulled the fairing last night.  Changed the fuse.  MP3 player worked fine.  Messed with the wires to look for anything loose, etc.  Thought (and still think) it could be the wire coming under the radio to plug into the aux (very ghetto).    None of this blew the fuse.  

Then, I paused the music and ejected the SD chip.  Bang.  Fuse blew.  Changed fuse - blew immediately - with MP3 not even turned on?  Changed fuse again, turned power switch to accessories - blew again.   Not sure what caused this but one would conclude that I in fact don't have this wired correctly.  

The instructions say to isolate one of the black/green stripe wires contained inside the harness bundle going to connector 27A and butt-splice one of the black wires from the music players to it.  When I initially did this, I made it a three way butt splice but I was blowing fuses.  I re-read this to mean cut the wire and connect the MP3 black wire to circuit 27A and tape off the other end.  Could I have this wrong?


An electician I'm not, but I've done a fair amount of electrical work and this seems straight forward - or not.

Do you have the electrical schematics for the bike? If you do you could trace the circuit you cut into to check your work. I would not think that the harness contains a spare wire that could be cut leaving one end taped off. You probably had it right the first time around. Did the install kit give you butt splices or the wrap around tap type connectors?

It sounds to me like you have pinched the wiring somewhere. The unit will likely draw more power when you eject the card. If you have a breakdown in the insulation on the wiring it may operate fine until you draw more current through the circuit or it heats up due to high resistance from the pinch or bad connection after it has been in use for awhile.

I think you were right the 1st time with the 3-way connection. I did this on mine and have not had any problems. I would turn the unit off before removing the card. Other than that i'm not sure what the problem could be. [smiley=nixweiss.gif]

DarrelH/Hd-Dude,

Thanks for help.  The kit came with butt splice connectors, not a tap scenario which made me assume that I was taking one of the ground wires which was seen to be redundant.   You're both probably right in that I probably miss diagnosed the issue and the the fact that the fuse didn't blow immediately gave me the false conclusion that the I should eliminate the green/black wire that from the connection.  

This probably was compounded by being unable to find 2A fuses and I used 3A fuses instead.  Just took longer to blow.  

Tonite I'm going to get another handful of fuses (I'm buying an electrical engineering degree in a series of 60 cent installments!)  and go back to my original wiring scenario and see if I can't find another cause.

Thanks for the feedback.

I cut that wire and taped it off on mine and have not had any problems. Be careful to get the right wire! There's a bunch in that connector.

[Bad Daddy]

mw8385,

I'm assuming you mean that you cut the wire going to the connector - taped it off and connected the mp3 to the 27A connector?  I'm sure I got the right wire, cause there's only two on the 27A connector  that are black with a green stripe (11 & 19).  Curious, which one did you use?

Thanks.

Hey BadDaddy - not sure what the wiring problem is on your ride, but I was blowing fuses as well, but then for some mysterious reason it stopped.  I got sick of pulling the fairing, so I positioned the in-line fuse to allow access near the bottom of the inner fairing.  PJ

I haven't done one of these so can't speak to where the harness lays.  But if there's a potentially serviceable part like an inline fuse why don't you just position it such that it could be gotten easily with just removing the headlight rather than pulling the whole fairing?  Even if you had to splice in a length of wire to get it to reach that far it seems an easier solution  [smiley=nixweiss.gif]

I will double check when I get home!

[Bad Daddy]

Agreed.  I definitely will reposition the harness to the bottom so I can get in under the inner fairing without pulling it.  Problem now is that any fuse I put in blows immediately so I'm still after the core issue.  Now I'm off to the bat cave to pull it all apart and start over.  Will update soon hopefully!

[Bad Daddy]

Ok, re-did all the connections.   Verified that the ground wire is off pin 19 of 27A off the back of the radio.  The other black wire connects to the Orange/White wire - There's only one hanging with the headlight socket.  Tunes were fine, sounded great for about 10-15 minutes.  Switched a couple different SD chips - worked great for a while - then bang.  Fuse blew and the next 4 blew also - without a SD chip installed, without the aux plug in (with and without).  The minute I turn on the accessory switch, without the MP3 turned on, the fuse blows.  Something's wrong here because if I even look at it, the fuse blows.  Five fuses tonite just trying different things.  Nothing works.  I'm considering trying pin 11 ground as an alternative to 19.  I don't know at this point.   Gonna have a (nother) beer and think on this.

[WFP]

are you sure there are no pinched wires or bare wires touching metal?

[Bad Daddy]

Well.  I tried everything.  Changed from pin 19 to 11 on the ground, three way, two way, nothing worked.  

Had the gun out, pointed at the temple, finishing the last swallow of my beer, and I think, hey, you took that module off the handle bar, but did  you really look hard at how those wires were positioned?  Another beer sitting on the bench called to me and said, for god sake man, at least give it a look!

No fu%($ng S*it.  The wires going into the back were twisted and I missed it.  Both times I looked at it, it looked fine, with a nice little dab of silicone and everything.  Let me tell you, That's a waste of good silicone, but that's another story.

At any rate, some adjusting behind the module and I couldn't make the fuse blow.  I abused it like a rented mule.  Pulled the SD chip in and out while it was playing.  Nothing will make it blow now.  

I'm gonna test it for a while before I seal the connections, but I think it's isolatd to the wiring going into the MP3 Player.  

So I'm gonna celebrate with that last beer in the hot tub and call it a night and hope this damn thing works tomorrow.

I'll save the bullet for a crotch rocket.

Wow, I bet it feels good to have found the problem!  Congrats and now you can get on with enjoying what's really a neat little toy!
