I have a slow drain on my battery and I can't track down where the
problems is. I spent this afternoon tracking down where the problem
might be. I thought it was with a modification to my lighting system I
did but I eliminated that and I'm still having the drain problem.

I just checked my system and it seems that both of my amps are showing
continuity between their power and ground terminals. Continuity also
shows between those terminals and the remote terminal. This doesn't seem
right to me.

When I put the probes from my old multimeter on the power and ground
terminals the needle swings all the way past 0 Ohms and slowly drifts
back past 0 Ohms and eventually stops around 1k Ohms.

Is there something wrong with my amps that's causing this battery drain
or is this continuity on these terminals normal for a disconnected amp?
Or is it some sort of stored charge on the internal caps that are
simulating this continuity?

BTW, the amps are PG ZXTi's, a 475 and a 600. The strange thing is these
amps seem to be operating normally.

Any ideas would be appreciated, this is really pi**ing me off.


What you're describing is a case of the capacitors basically charging.
That's why it starts at zero. Put your meter in current mode and directly
measure the current.
