Question about 2003 Harley Davidson FXDWG Dyna Wide Glide
My 2003 FXDWG Loses ignition and power to lights while riding. Engine backfires and runs but on very reduced power and lights dim. Signals cut out entirely. Sometimes am able to nurse it along until it cuts back in again. Other times I have to let the bike sit for a few minutes and it powers up again and it goes for a short distance and cuts out again. Resting is a short term fix but gets me home (if I'm not too far away). Will a grounding problem do this or an overheating relay ?
It never hurts to check your grounds, they have a habit of loosening up. It sounds like either the voltage regulator or the stator is failing to me. If you can get it to fail at home take a multi-meter and get a reading on the stator, I don't know the values on a dyna, but you should get a reading at idle and it should climb as you rev the motor. When my sporster did this it turned out to be the stator.

Sounds like ther passive rectifier. Exact same symptoms with my Vic 99 TC.
New rectifier was a complete fix.
