2015 Jayco Greyhawk

HELP!!
Need help with battery connections on my Greyhawk.
I installed a battery isolator switch and hand a low voltage shock on the chassis.
Now I’m lost and don’t know what wire goes where.

How many wires do you have? On my 2020 Greyhawk, there is one 2GA wire (black with white tape) on the negative terminal that goes to the frame ground. The other four wires connect to the positive terminal:
Red 2GA goes to Hydraulic levelers
Black 2GA goes to the generator starter
Black with yellow tape 4GA goes to battery disconnect solenoid
Black 4GA goes to aux start solenoid (alternator charging circuit)

Should be easy to identify the ground wire by tracing it to the chassis ground or by measuring resistance between each wire (disconnected from battery) and chassis ground.
