Ford vs Chevy Build-up

[Tony Corley]

As long as he has a good alternator, his pulley sizes are fine. I have ran the same pulley set up on 7 different cars with no issues, although I have always used Powermaster 1 wire alternators.

I'm going to try this one guys... http://www.summitracing.com/parts/tff-70686g

Listed for '85 models, but I don't see any difference in the case. Funny how the old one on the Camaro has never had an issue. What's the cheapest alternative in a Powermaster Tony?

That's for a serpentine belt, one of those set ups with several things running off the crank pulley. I don't know if it will work correctly with the simple set up you have now.

What happened to your alternator sounds just like what happened to mine. It was a one wire that charged at idle and then just quit, except mine continued to put out a high voltage of around 44. I popped a rubber plug off the top of mine to expose two terminal connections and jumped the drivers side one to the BAT terminal on the alternator. It allowed the output voltage of the spinning alternator to turn the charging circuit on. It outputs 13 some volts at idle now.

Once I realized my one wire could be set up as a three wire, I used post 4 in this thread for the wiring:

I have no ignition key, just a lever for my battery cutoff in the trunk so I skipped the wire to switched ignition part. No issue with run on.

I am using the serpentine pulleys/belt Dale. Still using the ignition key in the column...all I need is a alternator that will not fail. I don't really care what the rpm cut-in is...all I need do is blip the throttle one time and it will charge until the key is turned off. Probably need to install a voltmeter so I will know it is actually working at any given moment. I should'nt even need a battery charger with this car...with both fans and the pump running it takes very little time to cool down.

Voltmeter is a good idea. It helped me with my electrical gremlins and it's cheap. I didn't notice the idler pulley on your system. Good luck.

Note: Voltmeter is just voltage and will tell you how much juice is flowing in your system. It will let you see if your system is draining juice or holding at charge while running. Amp meter is more complicated to connect and will tell the amp output of the alternator.

EDIT: I looked back through your photos and I still don't see what I'd call a serpentine belt. Maybe we have the same thing in mind with different terms. I call what you have in the photos a V belt. It just runs the alternator. Serpentine runs multiple devices:

It's a serpentine belt running one device...straight from the alternator to the crank pulley, no idler. I went with it because I originally intended to use the factory alternator. A v-belt would not work well on these ribbed pulleys.

Seems that ribbed belts are called serpentine without regards to how long they are or what they run. Learned something today.

Go play.

Serpentine belts the groves run the length of the belt--- Cogged belts the grove run across the belt--- cogged belts use pulleys that look somewhat like gears -- you can also change the rpm of the pulley ever so slightly by altering the tooth count of the pulley- dry sump and fuel injection pumps are good examples of cogged belt uses---- while serpentine belts use pulleys that the groves look like circles on the surface of the pulley and you are restricted to only a few different diameters -most modern automotive systems use them generally in conjunction with either an idler or tensioner depending on the application

Thanks Tony...I'll go with it.
