99 Yukon Starter Relay Constant On - Draws Down Battery
My battery draws down in about 2-3 days parked. Isolated problem with VOM meter and pulling one fuse at a time in engine bay fuse box. The IGN A fuse (40a) is the culprit circuit. I then pulled the Starter Relay and noticed it was hot. When I plug it in it goes on. I checked ignition switch wiggling it to make sure it wasn't still in on position. No wiggle there. I doubt it could be the ignition switch, but you never know. I put VOM meter on Starter Relay coil terminals in fuse box and the circuit is constant on regardless of ignition switch position. Car runs fine. Now I have to pull the IGN A fuse everytime I park to keep battery from draining.
I'm trying to find electric schematic of that circuit to no avail.
Anyone have suggestions?

Replace the relay. I had one a while back that drained the battery, traced it to the power antenna relay. The relay tested as good, but it still drained the battery. Replaced relay, and problem was gone.

Forgot to mention, swapped relay with AC relay, same relay # 3604. Beside, with relay unplugged from box and VOM meter in the two slots that power the relay'* coil, the meter shows constant power to the relay coil. So, something is not shutting off that circuit when ignition turned off.
Thanks for the quick reply though.
