    the terminals that stick out look a little long? will this fit a 67 regulator plug?

    after all this conversation i finally accomplished the conversion. the only thing is now the alternator seems to be getting really hot. To where i can bareley stand to touch it.

    Is this proper for it to get so hot? the charging system is running fine.

    The only thing is that one of my water hoses run right on top of it and looks as if the heat is slowly melting / deforming the rubber. should i just get a longer belt so it sits farther away and leave it alone?

    Melting off water hoses doesnt sound fun:error: .
    And from my expierience on new era cars, alternators doesnt get so hot that you cant touch 'em.To be honest even on my previous car where the alternator has been placed about 8 inch from Turbo Charger i could touch it.
    Check if the alt has good grounding.
    My 2 cents:beers2:

    Thanks

    heat is usually resistance, make sure your cables are good, good ground and are the proper size. You did just get a bigger amp alt, you may need to upgrade your wire size. Go back a few post that that faq I posted, has a wire size chart for so many amps.

    i do have that document but it looks as if this alternator is self grounding.

    How would i ground this otherwise? there is another bolt in the back for a bracket, can i ground off of that?

    When i installed the alt in my factory bracket there was room for it to move freely and is held taught only with the top bracket.

    The alternator case grounds to the engine just fine, no need for an external ground. What he's suggesting is looking at the quality of not only the battery's negative connection to the engine, but the ground strap between engine and body (should run from rear of right cyl head to firewall if I remember right).

    I remember having a similar symptom years ago, still racking my brain trying to remember what I discovered as a root cause.

    That would be the battery ground to check, juice flows in a loop. The alt can't shove juice into the battery or system, any faster then it can loop back to it.
    If the battery ground cable was to small or funky, it can cause resistance, which can cause heat.

    A good ground should be as big or bigger then the feed and as short as possiabe, bolted down to good clean metal. Can't have enough good grounds.

    Be suprised how many things a good ground can fix.
    In the VIrago world it fixes charging and spark problems weekly for new folks.

    ill take a look at that strap thanks. is it a thick wire?

    the ground from battery-frame is fine.

    Im just a little confissed because the old alternator i had in never ran that hot. I could attempt an external ground on the alt and see what happens. I do recall the alt being a little loose in the bracket but i didnt think much of it.

    nothing could cause this from the wires running out of the plug or where the old regulator used to be?

    The ground strap should look something like this, but copper in color.

    back of the right cylinder? Where the tranny meets the engine? and runs to the firewall?

    Ive never seen this

    Yep, if not there, it'll needs to be somewhere between engine and body. This prevents the transmission, fuel lines, brake lines and exhaust from providing a less-than-ideal path to ground.

    Thats a problem some times as folks work on a car and dont think they need them extra ground straps and toss em, or they get in the way, or just forget.
    But they are needed, grounds are good.

    [We suggest folks run 3 main ones off the battery for the Virago.]

    Faulty grounds can cause electrolysis and cause pinholes in your rad or heater core.
    Stick positive lead in rad cap hole in the coolant with engine running and ground Neg to the battery Neg. Shouldnt read more then 0.1volt DC .

    cool thanks.

    any other suggestions if the strap is indeed there?

    grounding the alt with a wire? Can the battery cable cause this (the one from the alt)?

    If the ground is still there and in good condition, I'd check the main alternator output wire, it may need to be upsized - although at idle with little load the alternator shouldn't get that hot.

    What's the voltage with the engine running? The regulator may be 'stuck' in full charge mode. :Do No:
