Thumbs up AAW Classic Update power wire

Hey guys, I am working on installing an AAW Classic Update for my 69 and the inst. details running the power wire to the starter "B" terminal along with the alt. wire and the cable from the battery. I am considering running the red power wire to the junction block next to the battery to keep from having three wires landed on the starter. I will also have the power (fused) to the electric fans on this same junction block. Does anyone have any recommendations for or against this?

Thank, Dan

Re: AAW Classic Update power wire

I have started installing the same kit for my 69. I rewired under the dash and rear of the car but not the engine compartment but want to drive it home. Can I connect the stock harness under the hood to connect with the new fuse box i put on the firewall you know>? That way i can move the car then rewire under the hood with the rest of the kit later. thanks

Re: AAW Classic Update power wire

Before I did that I would compare the new block to the old to make sure the original front wires match up to the correct location. Good luck

Re: AAW Classic Update power wire

I really like the system from MADelectrical.com. I installed a new harness from Painless but used the MAD system to power the dash, charging circuit, etc. They have great diagrams on the website if you choose to go that way. It makes a lot of sense too. Basically the charging and remote sensing wire from the alternator go to a junction block on the firewall. The dash harness power wire connects there and you can send power from there up to another junction block or the horn relay on the radiator support. Don't forget to use proper fusing to power wires. Relays are always a great idea too.

Re: AAW Classic Update power wire

Ok, to get back on track here to the OP.

Dan, don't worry about having the alternator charging lead going to the starter terminal instead of the OE junction block. I had the same question, and Donny Bock at AAW explained why they chose to design it the way they did. I'd have to go dig out my notes for his exact reasoning, but I think it was that it would charge more efficiently and trigger the charging more efficiently, and that since the OE horn relay buss, voltage regulator, and the like were all eliminated in the Update, there was no reason to keep the OE junction block.

I did run my alternator lead up the engine harness from the starter a few inches, across the firewall on hooks under the heater box cover (same type of hook as the one on top for the heater fan lead), over the top of the inner fender (under the fender), and then out to the alternator with the wire for the "gen" light. I didn't want the wire along the oil pan rail with the battery cable, just because I didn't want a single wire popping up at the back of the alt, and then another single wire coming over from behind the battery for the gen light.

If you want the AAW explanation direct from the source, call the 800 number and use the dial by name with "Bock". Donny has forgotten more than most of us know, and even though he is now head of R&D (or some fancy title like that) he is still willing to answer questions.

Re: AAW Classic Update power wire

Began install under the hood and in an effort to hide wiring, I am routing the wires between the inner and outer fenders through wire loom. Where the wires run to the alt. and compressor, I actually used toilet risers (the chrome plated copper tubes-3/8") mounted to the upper valve cover bolts with adel clamps--looks pretty slick. Just cut to fit--around 16"-- and deburred the ends

Re: AAW Classic Update power wire

The only caveat to hooking the charge wire up to the horn relay, junction block, or starter lug is if you have a factory ammeter. Depending on how you hook it up, the ammeter may show discharge but not charge (or visa versa). If you don't have an ammeter, don't worry. I'm sure it will work fine however you connect it.

I am getting ready yo install my AAW harness and have been contemplating how to hide the engine wires (alt, electric choke, water temp, etc). I would like to see a pic of that if you can post one.
