Power Distribution Mystery...Do You have a clue?

Post by GRHuttman »



GL 1800 2003 Trike. The issue is with power distribution. New battery was charged and installed this morning. Had power before battery was replaced. Now none.
Fuses are all good.After four hours every wire has been twice and cannot find the reason-am I missing something or is it likely the alternator or starter (which was replaced in 2010)?

Hoping to travel to the Smokies Thursday but won't be going anywhere without a resolution. Only have 350 miles with the new trike kit.

Please explain why you do not strongly suspect that a BAD but NEW battery was installed?

I'd get that new, freshly charged battery load-tested.

My alternate method would consist of connecting a headlamp or similar load directly to that suspect battery.
But I live close enough to an auto parts store that I would simply get it load-tested.
When all else fails, RTFM!

I take it that the old battery was traded away when you got the new battery?

Are you sure the battery terminals are oriented correctly - just like the old battery? :shock:

Does *anything* light up with this new battery?

Hopefully you replaced the battery with an identical unit. I'd hate to think of the problems you will have if you replaced it with a battery that had the NEGATIVE and POSITIVE terminals reversed compared to what was removed.

Did you check the battery voltage at the battery terminals before and after the battery was installed?

The battery terminals are correctly placed. Indicates a blown main fuse but fuses are all good both the 100 and 70 and all secondary.
Nothing will light with this new battery. Performed continuity check however the positive side of the terminal indicates ground (and shouldn't) and the negative side indicates ground too without the battery hooked up just the leads on the trike. It is probably simple-maybe a bad ignition switch?

Appreciate the feedback everyone. The battery was successfully load-tested.

Since Thursday has come and gone, was there any resolution to this? Some trike kits have a wire that is attached to the negative battery post and if it’s accidentally attached to the positive post, it does weird stuff. I can help find the culprit if it’s still down. Fuse #2, 30A Main fuse A, will kill everything because it kills the ignition switch circuits if blown.
