My autozone blower is working great, now that I did the big 3 mod it works even better.

Just replaced mine today with the autozone blower..now my toes feel like their on fire! It came out no problem and literally took about 30 minutes.

so I jumped right into the big 3 mod. I can't see the back of the alternator very well. someone please tell me or send of pic of which post I'm supposed to mount the positive battery cable to.

Thanks!

...and 4crawler, thanks for chiming in. The fan blows super strong when hooked up directly to the battery - was blowing dust out all of the vents. I found that the rig only had a battery ground going to the engine block and nothing to the chassis or body.

I spent the majority of the day driving around getting parts and making custom cables, it got dark and rainy before I got the battery all wired up to see if the fan issue can be solved by better grounding.

I'm picking up tomorrow where I left off. Just don't know where the battery cable connects to the alternator. Being tucked under the ps pump, it's hard to see.

there should be a large stud on the back of the alternator where the wire will attach. should be a #6 wire there already. I got some nice car audio terminals that had multiple wire connections so i ran a wire to the block and one to the body/chassis using #2 cable. I also did the alt. swap to a chevy 94A alt. so far its working great. lights dont dim when at idle anymore. plus i put in a new battery so that helps too.

Thanks. Which way did you run the cable to the alternator? Over or under the block? Sucks that the battery is on the opposite side. What size fuse are you running on that line?

I ran the battery cable around the front behind the radiator and fused it with a car audio 100A fuse. i did a thread on it in the tech section titled alternator swap.

I'm happy to report that my Big 3 mod is complete and it completely fixed my slower blower motor issue (along with dim headlights, slow wipers, etc). The battery was only grounded to the block and nothing else. I had hoped that there was another ground to the body or chassis somewhere but there was not.

I'm relieved that I did not have a fire from wires overheating in trying to ground.

Thanks everyone for your help! Your support through this project is greatly appreciated!
