    Default Formula Mazda battery cables hot when starting

    I have a 1998 Formula Mazda and when I push the start button, the battery cables get very hot.
    Any Ideas???

    A loose connection or corrosion inside the cables causing resistance.

    Are they the original cables from 1998? If they are I bet your problem stops if you replace them.

    I was wondering, ... not sure if this is worth the trouble, but maybe bypass your existing cables with other (newer) cables as a test.

    Probably easier to just replace them (including ground).

    measure the voltage drop across the cables while cranking -- if more than 1V you certainly need to replace that cable.
    If both the voltage and ground path test OK, then your current draw is likely the starter.

    Default Fuel tank (primary) fitting loose

    This might be bad???
    The fitting on the top of the fuel tank is loose and as I turn it clockwise it won’t tighten.
    Can you tighten it without taking the top of the fuel tank off?

    Doubtful.

    I took the filler plate off and tightened it, but in doing so I noticed some cracks in the urethane on the fuel tank. It ends up that the tank has to be replaced because it is leaking.
    so now I have a pretty big project
