What and How is this fixing intermittent no start, .. Mayo Performance solution Options

[Literati914]

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.

The relay allows your 50+ year old wiring system to provide the same (or better) power at your device than it had when brand new.

It's not just for starters.

I've relayed blower motors, audio systems, wiper systems, head light elements, fuel pumps, and a shitload of starters.

Anything mid amperage flow and above will live longer with a relay in it IMO.

Pretty much everything since the mid 80s have added relays for all of the above.

Most of my diagnosis procedures start at the relay box now-a-days and it's faster.

The relay ALSO protects your 50-year-old circuit from running heavy amperage loads through it.

This is especially helpful with ignition and headlight switches.

Absolutely Ninja approved! (IMG:style_emoticons/default/ninja.gif)

Only reason in my book for not using a relay is originality.
