Which batteries did you disconnect and clean, the chassis batteries (engine start) How many are there? Or the house batteries (powers the interior lights and bathroom exhaust fans and such)?
Since you know how to check for voltage I would start by measuring and recording your battery voltage at the battery. Write it down if you need to because it might come in handy during testing. Now trace the battery positive cable as far as you can looking for a junction block, a fusible link or anything that looks like it's not part of the wire. Check for battery voltage at that junction. If you get battery voltage great, move further down the line and keep checking. Alternatively go straight to the fusebox in the coach and see if you get battery voltage at any of the fuses. Just find a ground and then back probe both sides of each fuse to see it you have battery voltage.
Ground the meter and poke the positive into each hole on the fuses. You should get the same voltage on both holes. If voltage on only one hole the fuse is blown.
Thanks for your reply. I disconnected all of the batteries, 2 chassis & 4 coach. The coach side is working fine, but I can't find any power coming from the chassis side, I tried to follow the leads but after they come through the wall from the battery tray they go into a cluster of wires and I can't see where they go and I don't see any fuses on the tray side or the other side. I've checked the lead coming to the engine disconnect and I don't see power there either.
