MF245

[jtbuck]

Can anyone show me how to wire my MF245.
It has a Delco alternator and after I rewired the battery keeps going dead. So I decided to just disconnect when not using-what a pain. I noticed when connecting battery the amp gauge goes backwards with nothing on(something not wired right???)
It starts with the key swith as long as battery is charged.

You could have the amp gauge wired backwards, the voltage regulator in the alternator, or the alternator could be bad, you could also have something that stays on, and drains the battery (I think you may have a alternator problem). Here's something you should have a look at Delco SI Alternator 1-Wire vs 3-Wire Explained
