I have a slow draw down on my battery confirmed by doing amp test on battery. I then went to the fuse boxes and tested each fuse individually for any voltage going across and nothing on any fuse (yes I tested the two under the kick panel). Is there any other place to test for a drain on a ZR-1? I am thinking of pulling the CD head out and looking back there but as long as the fuse on the radio is not showing a voltage it is not drawing any power. I am stuck on this one. Thanks for any help.

Did you do a drain/ load test on your battery too?

Yes I did. Matter of fact I have a new battery. I am frustrated enough that I am considering pulling the plenum and tracking down wiring under there. I may have pinched something but I thought for sure it would show up in the fuses.

Before you do that, consider undoing the wires at the electrical junction behind the battery and testing one by one. You may find something there.

What's the draw with everything off and the meter connected
inline with the battery? Even with everything off there's always a small draw. I'm sure someone here can pipe up with what it's supposed to be? |

do the lights ever come on when you drive over an incline? Say a drive way or something like that?

Turns out the battery was defective and wouldn't hold a charge. Never had that happen before -- exchanged and all was good.

It happens. When thinking 4 legged animals, start with dog or cat, not giraffe. Start with the battery, your other tests have concluded no fused circuit had a detectable drain, which if correct suggests either a non fused circuit, which was suggested earlier, or the battery. Make certain that the cables are tight, and that the terminal bolts are not corroded. Good luck and keep us posted. ![]() Marty |

I had a similar battery drain issue a few years back after a trip to BG. Did the usual fuse pull trouble shooting and came up with nothing. Found the problem by first connecting VOM (set first in 10 amp current mode) in parallel to the negative battery cable. Then turned the key switch on an off without starting the engine. Removed the negative battery cable with the VOM leads still connected to the battery and load and found 275 miliamp drain remained after the CCM went into sleep mode. Pulled the easier to get to fuses from fuse blocks C7A & C7B located below the EMC to isolate the problem circuit. Turned out wheel polish had leaked on the plug connection of the radio receiver unit located under the storage compartment tray and the dried polish provided enough of a ground signal for that circuit to remain on after the key was switched off. Gave the plug a good cleaning and everything worked OK.
