My friend took his car to Ed Mayo of Mayo Performance to fix a no start after driving issue. Ed has been working on these cars since new and he knew exactly what the trouble was. He installed the item in the following picture and all is well now. He said they even used to have to do this to NEW 914s back in the day!
He explained it to my friend who only caught bits of the explanation. Something along the lines of the wire to the starter getting hot and needing a 1/2 volt extra from this add on, to overcome the issue. I assume it’s the typical heat related issue. BTW I think a lot of people assume vapor lock is the only heat related problem (fuel pump is in the front on this car). Can someone give a thorough explanation for what this is addressing and how? I’d love to see a wiring scheme of this fix also. Attached thumbnail(s)
