Default Re: Lost voltage to coil while cranking

get a 10 amp or larger dioed. now run a wire from the starter side of sol. on the fire wall to one side of the dioed flow toward coil. run wire on flow side of dioed to coil. now when you hit the starter you will get full volatge to coil. the dioed will prevent back feed to the sol.when truck starts
