My son has a 1978 Ford mini home with a 351 engine. All of a sudden it won't start. Took starter & battery to have checked and they are both OK. Replaced starter solenoid and ohmed out cable to starter. Should also say lights don't work now either.. What do I do next?

Re:1978 Ford minivan starter problem.. starter does not crank.. solenoid clicks but voltage is not present at starter.. head lights do not come on either. Battery and starter test OK at parts store.

Maybe you need to replace your starter or check the flywheel.. because we also encountered same problem of yours but we just replace a new starter and a flywheel...
