Hello How much trouble is it to convert to a internal regulated altenator and bypass the voltage regulator on a 756. Thanks ED

I"ve had a one wire on my 756 for twenty years without a hitch!
Only way to go!
All my Red has one wire!
Hot to battery and ground the alt. to the block. Done.

Presuming your 756 currently has a Delco alternator, swapping it for a Delco 10SI (internally regulated) alternator is straightforward.

Mechanically it’s a direct swap – the 10SI will fit the existing bracket and tension arm. And you can swap the pulley/fan from the old alternator if the pulley on the new one doesn’t match.

For the wiring:

1 – Find the wire at the old regulator that goes hot when you turn on the ignition. Connect this wire to the #1 aux terminal on the new alternator.

2 – At the alternator, connect the #2 terminal to the BAT terminal.

3 – Tape off the remaining wires at the regulator – they are longer used.

When I bought my Farmall 560 it had an external
voltage regulator wired to the alternator. It
was an old-style mechanical type and was not wired in properly. I was able to find a pin-for-
pin direct replacement solid-state regulator at a local car parts place and that, combined with
being wired in correctly solved all my issues. I
don't remember what it cost, but I doubt I paid
more than $50.00. If you want to persue that,
take the time to have a garage check the alternator output to make sure it isn't shot. If
the alternator is bad, I'd go with a rebuilt that has the regulator internal or do the single-wire thing. I don't know from personal experience
but have been told than until you rev the engine
and get some "tickle" to the one-wire, it doesn't
put out much. If that's true I'd rather go with a conventional alt/reg and have good output as soon as the engine starts.

Question: Which works best with an internally regulated 1 wire alternator, an ammeter or voltmeter?

I need to replace the ammeter on my 2606 with conventional alt & reg since the needle don't move. Assuming the alt or reg isn't already dead, whenever I have to change the alt, I'd probably go to a 1 wire internally regulated one. Getting rid of the regulator would eliminate one more potential trouble spot. Guess I should check the alt before I do anything. I don't run it long enough for the battery to go down so I've never worried about it.

For my money, I'd go with an ammeter no matter
what kind of alt/reg combo you are using. It gives you more information about what is going
on in your system. All a voltmeter does is tell you that you are building enough voltage that you should be charging. The ammeter actually
will tell you that plus whether there is more
juice going into the battery (charging), or more
coming out (discharging). If the meter shows
the direction is charging, then you know your
alt/reg output is enough to run your ignition, accessories, etc. and still have enough
left over to charge the battery. Normal operation is that when you first start, you'll
see 10-15 amps of current in the charge direction and then slowly fall off to just a
couple of amps after you've run for awhile.

Thanks. Ammeter it is.

Click here. Easy to change my 240U so should be easier for you. David............
