Does anyone know what gauge the positive and neg. battery cables are? (car is an '89 n/a) Im in town getting some new cable and of course I forgot to check and I dont have that car here to reference. :roll: My gut says its 6, but I want to make sure. Thanks!

According to the wiring diagram in my Bentley they're both 25.0mm2
A little more cross-section (26.65mm2) gives you an AWG 3, while a little less (21.14mm2) gives you an AWG 4, so take your pick.

Thanks for the reply! I measured last night and you just confirmed its more or less a 4. I luckily didnt get anything yesterday, since I thought it was 6, but Ill get the goods today. :cheesy:

Picked up all the stuff yesterday. Got enough to do all the positive and negative cables and all new terminals for $25. I think a new OE starter cable alone is $75. Although Im sure I will spend an hour getting everything to fit and soldering it, but hey, my time is free.

FYI I am a lazy *** so I always use 4Ga welding cable for my batteries unless they have to go to the trunk. Then it is 0 awt. Both my Saabs have the wires from the battery to ground, starter, and alternator on 4Ga. THey both seem to be happy. :cheesy:

Welding cable is highly conductive, very flexible, can handle heat, and is not that hard to find; just look up welding supply stores.

Im picky though.......I HAD to have red and black cables. :lol: Dont ask why, I cant explain it either.
