Not if they are brushless, which most are. The brushless ones have very low idle output. Up to you, I have one here if you want, but I think you are better with the one you just received. People tend to get hung up on the total output number, rather than output at idle, and then they get mad...

Mixed opinions. The larger alternators do fit and work, but do not charge at idle. I would say it depends more on your intended usage of the inverter. What is its rated (not peak) watts, and how many watts do you intends to use, and for how long? Also, when would you be using those watts...

If the alternator got hot enough to melt aluminum, then there is a dead short in it somewhere. Likely the diode bridge in the back, but at those temps it can melt the varnish off the copper wires of the stator as well. Best and safest thing to do is yank the pulley and ditch the rest of it for...

For the 250, the latest craze is to slot the 3 holes of the stock bracket on a mill. This allows you to align it easily. Still does not support it properly, but seems to work for most. I always intended to find a bracket for that engine as well, but never did. It was usually done by the...

Thanks guys. I only know how to get spot-on alignment with the 8.3L since that is all I own. Most all 250 engine owners have each done something slightly different from one another, regarding pulleys, brackets, spacers, bolts, and tensioner. The configs are slightly different, as the 8.3L...

Happy to help.

Correct on your #568. This is also why the civilian unit is a much superior unit. Some of the modern civilian ones can use an external remote sense, but if nothing is detected on this wire they default to the internal setpoint. The military one would instead just go full field because it...

It was more of an info post rather than a classified, for those that want to save $ and do it themselves. If you are interested in purchasing from me, PM we and we can go from there. 1 week lead time, nothing kept in stock.

pp, J is just being a tool. J, it depends if you smell this burning inside your truck, or external. ;)

Glad everybody is having fun. I don’t have or sell the 130’s anymore. The 24v 70 amp Delco 21Si clones can be had off the internet for $70-$100 delivered including 1 year warranty. They appear to be more reliable than the genuine ones, actually. The correct 8.3L Cummins bracket is $100 from...

Trying to keep the radar on for failure cases of them, but don’t see much. Many people using them. May even be better than the genuine thing, the voltage regulator quit in the genuine Delco I was benchmarking, in my avatar pic, less than 1 year old of hobby use. Soldered a replacement in, and...

eBay of full of nice ones spun from solid barstock, in both 8 groove serpentine and double V groove. 21Si and clone are 7/8" shaft diameter. Serpentine pulley is about $14 delivered, and double V groove about $18. Both may include a keyway broached into it, simply ignore this, it is designed...

Exactly. Others have been able to put this together and make it work. There is no one specific part number for this. Different alt part numbers change the B+ location. The pulley shaft is 7/8” diameter. That’s the last of the giveaways.

The Chinese Delco clones can be had right now new for $69 delivered including warranty. That pricing is so low that I don’t dabble in it anymore, unless somebody wants high output or genuine Delco. 70A is plenty for these trucks, even with aftermarket accessories. And, the Chinese units seem...

Understood and appreciated.

Which part is incorrect? Also your alternator should have been adjustable, and not required a regulator change to vary the target voltage set-point. This would be a good case of "Read the TM", I would support. CARMAN: I am really not selling alternators anymore unless somebody wants something...

They are not the same shaft diameter, plus the stock pulley is junk. Stock shaft diameter is smaller than civilian, stock shaft is keyed which is obsolete and not durable. Most all common civilian heavy truck alternators use a 7/8” shaft diameter, which is 0.875”, including the Delco’s and...

He's so excited, he meant to say alternator bracket. He can now now shut the truck down in any switch order withour an over-volt occurence, which otherwise typically damages the PCB, ABS module, and CTIS controller. This alternator is also not scared to charge low batteries at an idle, an...

See your 5 and raise you 10, for whoever is left in the ring.....

They will throw me off stage by the scruff of my neck and my belt loops if I post a price here. I will PM you the cost.
