The obvious question is - can you see the Pioneer front panel lit up?

Re: Parasitic Drain - Bulb Trick
 

Yes, jim's right, there is 170mA *after* the Pioneer's fuse is
disconnected. With it connected, the bulb glows brightly and it's too
high for my ammeter.

Strangely though, the battery has not discharged yet. I've left it
connected for two days now without charging/starting it.

And of course, all the measurements were taken with the Pioneer off,
front panel dark, "demo" mode off..

Hard to see how the wiring could be wrong, but yes, the standby draw
seems too high. I'll look into the manual for the specs. Will post
again ASAP.

Many thanks.

I'm not sure exactly what it should be, but 170 ma besides the audio system
is way high. I'd expect more like 20-30 ma, mostly for the alarm system.
