Work backwards from your last installation... If it was the winch, disconnect it entirely to determine if it is the culprit.

Where and how are you measuring the current draw on the system?

using multi meter i pulled every fuse and relay one at a time after removing winch and power wire to alternator just removed pcm plugs and droped to .10a
which i believe to be 100ma

That's odd that a winch would draw anything, even 150ma, when not being used.

There's a leak in there somewhere if that winch is operated by solenoids. No circuits operate or draw any current in a normal winch that is 100% solenoid operated. I can see where a winch with MOSFET devices instead of solenoids could.

I am still unclear on what you are trying to measure with the DVM... Are you chasing a ground problem? Measuring from a battery disconnect to ground may be giving you a "noisy" signal and a false reading.

ok so i put all the fuses back and realised that the winch was grounded not to my quick disconect and was showing draw from something else so

with everything hooked up proper i have a total of 260 milliamp draw with alarm stereo dual amps
also i noticed the amps alone draw 35-40 milliamps



is 260 milliamps normal draw

The only draw I would guess you should have is your radio (clock) and alarm system. Your amps should be connected as your radio is from the on and acc position of the ignition switch. 260ma sounds high to me. I had a defective On Star module that would kill my battery every time I didn't drive the vehicle for 2 weeks and the dealer said it was 250ma from what I remember. Check the radio in off position and the alarm system add the togrther and there is you answer.
