MF 135 Discharging battery

[Soundguy]

the voltmeter test to the back of the alt and bat posts tells you nothing except the wire is intact!

with tractor off, put a test lamp inline with alt and battery.. if it lights up, then yeah.. alt needs help.

if no, then pull + cable and put test lamp inline with bat cable and bat... lamp should light up if there is a laod. if yes, start pulling circuits one at a time till lamp goes out. when it does, last circuit pulled is the load.

Automotive alternators run at higher RPMs to charge also.

I put one in a Nuffield 465 and more recently in a 1939 GM pickup.
Both engines are low speed but there was no problem getting the alternators to charge.
