Installed a centech wiring harness 10 years ago when I built the EB. Had original alternator with external regulator. Alternator worked as it should until I installed AC, a pusher fan, and HID headlights. Stock alternator can't keep the battery charged when running AC and pusher fan.
Upgraded to a 130a 3G to handle the extra loads and winch. Doesn't seem to be charging properly. Never shows a voltage over 12.5 and drops when I turn on lights, AC, etc. I think my mistake is connecting the large yellow Alternator wire and the large red Bat wire in the Centech harness to the Bat+ of starter solenoid . I have a #6 from 3G to Battery terminal.
Anyone have similar issue and find the cause?
Thanks
