connected to the terminal behind the battery. So there's a lot of stuff to disconnect one at a time whilst trying to find the offending circuit. My best guess is to look for whatever aftermarket stuff you have first. The factory circuits that fail are likely due to sticking relays - like the fuel pump. Good luck ...

Re: Amp / Voltage draw issue.
Ok so i got my good multimeter and set it to volts this time...between the ground cable and negative terminal it read 12.83 volts. I flicked it to 200ma fused and it pegged and popped my fuse. Sooooo maybe alternator diode??

Re: Amp / Voltage draw issue.
What brand and model meter? There's a "rush" initially like mentioned earlier. Set your meter to AMPS not Ma and make sure the cables are in the correct ports. Set to AMPS before using! It sounds like you're mentioning you switched it "while connected". Don't know?

Re: Amp / Voltage draw issue.
Ok set the meter to the 10A setting. Leave the black lead in the middle plug. Put the red lead in the left plug. Assuming you have the + off the battery. Red goes to battery + black to + cable. Everything off see what the drain is.

Re: Amp / Voltage draw issue.
Well dumb old me...i didnt pay attention to the ac/dc settings. I switched it to 200m dc and it reads a 2.7
I blew the fuse on the 10 amp leg. I will see if i can find a replacement tomorrow.
