I haven't done this, but Of course I don't know if previously someone had done this or something else destructive. people give up on engines because the distributor is stuck or the alt broken, they really do!
Are the brushes in good order and the armature clean? If your light starts to dim when you give it some revs its maybe making a better contact but you should see at least a small voltage rise on the output
Found this on the net, is it good advice? If yes what does he mean by arc. Unplug the harness from the regulator. With the engine running, connect a jumper wire from the connector’s B+ Terminal to the connector’s Field terminal. Only do this for 30 seconds at a time. The engine will bog down. The alternator should have an audible whir and ramp up to max output. If you see a visible arc, repair or replace the regulator. If there’s no arc, the alternator has an open Field circuit or worn-out brushes. Fix or replace as needed.
Pull the reg and inspect the brushes If they are worn down to much or damaged they can't pass the voltage to the reg On type one alternators they are part of the reg id imagine type four to be the same
That makes no sense to me, the regulator is on the firewall, the brushes are in the alternator which is attached to the van and very much enclosed. you have to strip it down to get at the brushes. I don't want to do this is there's no point, it'll take hours.
Surely there's some way of testing this fecking system with a meter and determining whether it's the reg or alt at fault?
I learn as I find broken things dude, just like yourself I imagine, neither of us being time served vehicle mechanics.
The light goes out with revs now, but comes on again as they drop. That's with all disconnected from the blue reg wire @Fish Thought you did too, so what shall I test Paul?
I think I've worked out the reg is probably fine, but the alt isn't getting "exited". what to do? Take it out and have a shufty at the brushes and commutator. Class
