Then run a larger wire directly from the battery to the B alternator connector through a fuse. This was suggested earlier by Brian894X4, but I dont think anyone caught the simplicity of it. From what I can tell, this is a legit solution, but please correct me if I'm wrong.
Second, where can I source the parts circled in red:
I know I can probably get the blue sea stuff from west marine, but what about the battery terminals? I was just going to buy the whole harness from urban land cruisers, but I think I'll just build my own.
Thanks! |
There are two white wires in that “B” terminal connector on the alternator. One charging big white wire goes to the battery positive and is protected by connecting through about a #14 fusible link wire in the AM1 plastic box. The other white wire at the alternator “B” terminal is about a #10 gauge wire and sends power to the under hood fuse box. Before it gets to the under hood fuse box it splits and supplies power to some circuits in the dash fuse panel. So in this stock configuration power is coming directly from the alternator on this #10 wire to supply these circuits.
If the wire is just removed from the alternator and a new heavy wire is run between the alternator and the battery positive, the under hood fuse box and the under dash fuse panel circuits are now being fed back through the #14 fusible link wire. Like this – power from alternator up big new wire through new fuse to battery positive – from battery positive back through old 14 gauge fusible link wire through old former big charging white wire then to old 10 gauge white wire to fuse panels. It will work, but all those circuits could have less power since they are being back fed through the smaller fusible link wire. To say it another way from faulty memory, the headlights, EFI, tail light relay, defog, FL heater, ECU B, and OBD will now all be fed through the 14 gauge fusible link. Hope this makes sense. Sorry I do not have that version EWD.
Wrangler NW among others has those items circled.
Hope this helps.
