Hi,

Im in the midst of putting on my D series wiring harness on the H22a after i sleeve it and make it look all new, However I am curious how to wire up the alternator and starter.

I realize on the oem EG hatch there is a wire from the alternator to the fuse box in which case that lead is a +12 always on looks to be 8 gauge wire.

Then on the Starter motor there is a lead that goes to the +12 on the battery in the engine bay.

However My setup has one of the oddsey PC680 batteries located in the rear then a single 8 gauge wire going to the fuse box located in the glove box, then I have a single 8 gauge lead coming off the alternator section ready to be run into the engine bay.

The question is, Can i simply run a lead from the alternator to the starter then into that spare 12v lead coming off the fuse box? rather then running another 8 gauge wire directly to the starter?

 

Sounds to me like that means when you start the car, it would draw from the battery through the fuse box to the starter, Does the 12v lead in the engine bay to the fuse box connect at the same point as the wire from the rear mounted battery on the fuse box? If so I say you are safe that way, but in all honesty, for the alternator to charge through the starter contact and fuse box contact to the battery, I would use thicker wire to get good juice all the way back, 4 gauge at least, 2 or 0 would be better.

 

well looking at

it appears that 8 gauge wire can withstand 73 amps of current.

I don't think my h22a starter can draw that much power but I may be incorrect in saying this, most likely i probably am.

Although the bs they tell you at car audio shops about amp size and wire load haha BULLSHIT.. but thats another story..

The alternator wire along with the + lead that go to the fuse box seem to be only connected via a internal copper bar, no fuse between them.

also the original wiring from the starter was 8 gauge wire. I know I'm most likely stretching the limits running 5 times longer wire although there really isnt any way for me to run a thicker gauge wire to the fuse box or it would look like ***, plus I had 20 feet of * gauge wire spare from when i bought the car and my old amp install.

I Suppose I can try and see what happens if i feel the wire getting warm then its probably not going to be a good idea, although I don't believe the car in normal operation mode is using much power while running since its being drawn from the alternator in which case that length of wire would be quite short from the alternator to starter to the fuse box in the glove box.


any other suggestions anyone?
