I have a 55 Chrysler 1970 model 557ha that turns over fine has good compression new coils and new key switch but will not start. There is a breaker switch on the side that trips as soon as the ignition turns over. I disconnected the stator wires to the rectifier but it still isn't working. The motor has been sitting up outside for several years. Are there any other thing I can check also replaced the flywheel key the old one was broken. Points have been cleaned and look new and the plugs look fine. Any help will be greatly appreciated.
