Mystery power drain

[Beachbummer]

Thanks. The radio Is fully switched, so when the dash switch cuts power to it, off there should be no drain possible, but I'll keep checking.

I did notice as soon as you provide current the current jumps to. 16 and after a few seconds it drops to .03, so as if the ECU or something else wakes up and uses a little power, then shuts off and something parasitic is draining my 30ma.


I have added a few relays (for an extra horn and for the extra bilge pumps) years ago. and I have heard when they go bad they can possibly not open fully and can cause parasitic drains.

Thanks again for your ideas!!

So when you provide voltage the current “jumps” to .016 then drops to .030? .016 is less than .030…

Sorry... Extra zero... Jumps to 0.16 for a few seconds, then down to .03.

I corrected it above also. Thanks!
