Alternator took a dump..any suggestions on what I should buy?
thanks

 

I bought a 100 amp, plug position was in a different spot but everything reached works good. I just wonder how the ambulance package one would work.

 

Is 100 amp what I need? I know these trucks need a fair bit of amperage and I don't wanna get stuck with the wrong one. What's the ambulance package got? I'm assuming high amperage and more accessory connections than I need but I don't know. This is my first IDI charging system failure and I don't wanna install some crap that will fail or over charge my new batteries

 

I think the smallest they sell, which I would assume is stock is 60 amps. If i recall the ambulance one is 110 maybe. I know the 100 amp is working perfectly in my 90 model IDI

 

I upgraded to the 130 3G alternator. In my opinion it is a must. At idle the volt meter doesn't flinch it charges well and is worth the upgrade!!! You won't be disappointed!

i also like it because it is internally regulated vs the external regulator

 

+1 on 130 amp 3G upgrade. Only way to fly. Lights won't flicker when glow plugs cycle.

 

Third on the 3G. I found my 3G in a 90's taurus in a pick-u-part junkyard. Took the wiring harness with me. Only took a half day to rig up. Here's a good tutorial: https://www.ford-trucks.com/forums/8...-pictures.html

I had so many problems with my 1G even after I would change the VR and alternator out. But once I went 3G, never had any problems yet.

 

3g all the way

 

Wrong, these trucks hardly pull any amperage. My '86 pulls 33.1 amps with everything turned on for maximum electrical load. A gas truck will use slightly more for the ignition system. The early trucks came with a 42 amp alternator which was entirely adequate but might not make 14v at idle depending on load.

For a bolt in replacement a 65 amp 1g is fine. I recommend swapping to a 130 amp 3g as it's only a little more time and money. The 3g is a superior design, the 130 amp will output nearly 100 amps at idle IIRC and oversizing the alternator will ensure it runs cool.

For a vbelt system a 130 amp alternator for a '95 E-150 with 300 six is clocked correctly and has the right bolt spacing on the mounts for our application.

 

The junkyards are full of 3gs. This is the write up I followed

Gothcha! I was wondering why it has a 70amp on it now. Anyway thanks ya'll, I will be looking into the 3G a little later because time and money are both running thin after all the other repairs I've done in the last month. Thanks for the input!

 

I did my swap for less than 50 bucks

 

Easy swap for sure! Unfortunately I just do not have the time at the moment to search junk yards for a ford taurus and a crown vic. I'll get me an auto parts store one for now and keep my eyes open for the 3G swap in the coming weeks.

 

If you don't want to scour the junkyards, you can just order a 3G alternator from Rockauto and order the conversion wiring off of ebay. Something like this:

well, that's good to know as well! Don't get me wrong, I love sifting through junkyards, just short on time at the moment. (New born baby and a five year old boy) I got a 70amp motorcraft to get me by till I do the 3G upgrade witch I look forward to doing, cause I love tinkering with these old trucks. Thanks for all the input ya'll! Your collective knowledge is priceless
cheers!
