Delta 88 has a current leak somewhere. We put a new
battery in it, the next day it was dead. I'm fairly sure
the alternator is OK. My plan is to put an ammmeter
between the POS lead of the battery and the battery
cable, then pull fuses one by one until the current
drops to 0, and then trace from there. I'm guessing
there is a bulb or some other low current device that
is staying lit all night. Any other suggestions?
Before disconnecting battery, check for alternator
diode leak by disconnecting fat battery charging
wire from terminal on alternator then connecting
ammeter between wire and terminal.
Note: It is a hot wire connected directly to POS
on the battery. Avoid grounding the wire, tools or
ammeter during removal, testing and re-installation.
