Well. The dealer would not honor the warranty. Said since the heated grips get warm they are working! Ha! Yeah, the are warm, not hot when it gets below 60 degrees.
I purchased another set, installed them and same thing!!!! Must be an issue with the CVO wiring. It says right on all the heated grip packages that "will not work on CVO." What the heck. So when I check DC on one side of the circuit, the V drops to 6 V, and back to 12V when I turn off the heated grips. On the other side of the circuit, the V drops to .4 V when I turn on the grips and back to 12V when I turn the grips off.
On my 2018 FAT BOB, it has OEM heated grips. On the white wire side of the ciruit, the V stays at 12V when you turn on the grips and turn them off. On the black side of the circuit, it drops to 6V like on my CVO. The difference is the drop in V on the white side of the circuit.
Anyone have any idea what would be causing this. Short in wiring on the TBW side? That is the only thing I have not replaced, athough I have continuity from the connector to the end of the TBW cartridge on both sides of the circuit.
