You have no other choice now that you have surpassed the 50th post mark on this issue without a resolution…….. let the spending begin!

@wjburken not even sure what the opening shot should really be.

I don’t know if I missed it but you def checked your positives and grounds? To and from battry?
Start run relay? Check all relays? Etc?

@PG01 battery connections are clean and tight. I haven't put eyes on the battery ground to the frame yet (or the engine or wherever it goes) and it probably wouldn't hurt to clean up the frame ground that's under the drivers door.

Well, damn. This is one of the first steps! Check that main ground on the other end where it bolts to the engine block, a few inches behind the power steering pump.


*EDIT* I'm a dumbass.

Well, damn. This is one of the first steps! Check that ground on the front of the passenger side cylinder head. It's the easiest to get to.


It took way too long to find this pic off the 'net. Ignore the blue aftermarket wire. The factory ground is the black 4 gauge with the exposed copper. It's just inches away from the oil fill neck:

Interesting. I was curious enough about this to go look at mine, and it's not there on my L59. And the oil dipstick on mine is closer to the firewall.

Check the other head.ain’t the battery on ds in NBS? I forgot how mine was setup but I’m pretty sure about battery placement…. Little red junction block for the positive too?

Yes, red junction box for the positive, and battery on DS. I think the main (fat) ground goes down to near the starter.

I used to have a ground schematic for the nbs and nnbs but I think I deleted it….oh well
