Ok guys, this one has had me puzzled for a week, this rusty little junction box is mounted to the frame, just forward of the starter on the passenger side of the vehicle. It looks OEM to me but I’m not sure, I’ve owned the vehicle for 13yrs and I’ve never changed, swapped or even seen it. 2 of the wires run directly to the starter, the red & one of the black ones.
I recently had severe voltage drop when using my windshield wipers (9v) & slight drop when using blinkers and reverse (lights). So I started tracking down the culprit, cleaned battery terminals, replaced fuses, new ignition coil, fresh grounding from battery to frame & block, new alternator. They all gave me slight improvements but nothing major until I cleaned and rewired this junction box. The truck is currently idling at 13v but should be stronger with all the improvements (drops to 11 when wipers are on high). All my grounds are clean and tight, I’m 99% sure this is coming from the positive end of the feed.
Does anyone know what this junction box is? Is it aftermarket? OEM? Most importantly, where can I find a replacement or a work around?
