[Farmall] It's Battery Time

[Mike Sloane]

I have converted several Cubs to 12 volt alternator, and the only trick 
was to rig up the mount so that the alternator lined up with the belt. 
It took a little fiddling, but it was worth the effort. I did the 
conversions many years ago, and the only alternators that were cheap and 
small were those from some Chrysler Corp. smaller cars. These required 
external regulators that I mounted in the same place as the original 6 
volt regulator. Based on what you say you have, I would spend some time 
with the alternator mount to get the belt lined up and stay with 12 
volts. One sourced of a "universal" mount is T.H.E. Company 
(www.the-co.com>, but I am sure that you can probably find them 
elsewhere. The universal mount is very flexible and can be arranged to 
mount virtually any alternator on any engine (well, I am sure that 
somebody will find an exception, like the gear driven generator on an 
old Cat 4).
