Full DC conversion question
Doing a full DC conversion on my XR650R with a Ricky Stator, Baja Designs regulator/rectifier, Tusk dual sport kit, fan, and battery setup.
Battery, Tusk harness, and regulator/rectifier are all connected together on the same positive/negative bus connections.
When the bike is OFF, everything works perfectly off the battery. But once the bike is running, voltage becomes extremely unstable — jumping between ~11V, 13V, 18V, even 19V.
The Baja Designs reg/rec is brand new. Stator is older but was working properly before the conversion.
Main things I’m wondering:
- Does the Baja Designs regulator/rectifier need its body grounded directly to the frame?
- Or should the black ground wire back to battery negative already be sufficient?
- Could this simply be a loose/bad ground somewhere?
- Any other common XR650R full DC conversion issues that could cause this?
Trying to narrow down whether this is:
grounding issue
bad connection
floating ground conversion issue
faulty reg/rec despite being new
Any insight appreciated.
