Re: Help... MG suddenly won't crank
Hi Royce,
A quick check is to turn on the lights, & hit the starter. If the lights dim way down, or go out, It is likely that the battery is low or there is a high resistance connection in the path from the battery to the starter or in the ground path. If the lights stay bright, there is a problem in the starter, the solenoid, or it's circuits.
Another quick check, hold the starter switch on for a while. Then feel the battery & starter cable connections for heat. If the battery is good, a bad connection will get noticeably warmer.
