After my recent melt down under the dash, I got rid of the amp meter and replaced with a volt meter. Not sure if the newer cars are wired different. On mine (1436) the main output wire from the alternator goes to the fuse panel, from the fuse panel to the amp meter, then out to the solenoid. So all the power was running through the dash!
I removed all those wires and ran the main output wire from the alternator (bigger wire) to the solenoid, then I ran a new wire from the solenoid to power the fuse panel. Installed a new volt meter and hooked a switched wire to it.
