can every single car module cause a short circuit? my test light stays on between batt and terminal unless i unplug every single module? any advice?

Randomly testing between fuses will be confusing. You will get different results depending on whether each circuit is live or not.

If you got such a high resistance at the fusebox then there is no short between positive and negative. To be honest if there was a short like that you would be seeing blown fuses and/or melting wires.

lets say i suspect a circuit is bad , how can i test that specific circuit for a short? im following a mitchel diy guide and its telling me if my transmission harness has less then 10k resistance between harness and ground that i have a short, and my reading was 0.3 for for that specific wire.

Is that referring to testing CANBUS lines to ground?

no its transmission range sensor to ground. also do you know if that 1.7 m ohms means anything between positive and negative cable no battery connected?

But I thought the 1.7M was between positive and negative of the fusebox?

If you get an incorrect reading between transmission sensor and ground, have you tried unplugging it?

no the 1.7 is just between the positive and negative cable, i just tested my test light between 2 fuses on the fuse box with out ground connected to test lightand it lights.

Sorry but I think we're going round in circles here. I'd recommend an auto electrician has a look. One with a decent code reader and knowledge of fault finding.
