Hi all!

I joined the forum because I need advice, but I'm happy to hear about others' experiences with their Chevys. I have a 1975 El Camino I'll be discussing later, but right now my issue is with my 1997 diesel Suburban 2500. It's drawing about an Amp from the battery with the key out of the ignition, doors closed and hood light bulb removed. The current drain has made it difficult or impossible to start at times, particularly in cold weather (yes, I also need new glow plugs). Through methodical work with my multimeter, I have narrowed it down to a circuit the fusebox calls Ignition A, which has a 50A fuse. I am going nuts trying to find a wiring diagram online, and I'm hoping there is someone reading who can help me locate one, or at least give me some clues as to where to start looking for current draws in this circuit.

Also, I'm planning on rewiring the batteries at some point, putting an isolator between so they're not just wired in parallel all the time. I'll be discussing this later in life as well.

Thanks in advance for any help anyone has to offer, and I look forward to chatting with all of you.
