My 1200 has been going through starter switches to the tune of one for every six months of daily driving. I stumbled upon a 4WD board, and some guys there were having the same problem with their older 4WD Japanese-made trucks. They claim this alleviates that problem entirely.

This is a Painless Wiring "Hot Shot" starter relay originally designed to be used with a motor that has been transplanted into a hot rod. Apparently, when you stuff a big motor into a small space the exhaust generally runs very close to the starter and makes them hard to turn over when they are hot. This is a booster-relay system that is supposed to overcome that problem.

This system has an optional "bump" switch which is like having a remote starter switch wired up. Comes in handy if you are setting points or checking fuel pump operation, etc, etc.

It's too early to tell if this will alleviate the "Start" position failing on my last two ignition switches, but I strongly suspect it will. The system was almost idiot proof to install, and my 1200 cranks over MUCH better than before.

The option bump switch kit was about $55.00 usd shipped, and the relay-only kit (no bump switch) is about $10 less.

I installed it over the Christmas holiday and have been very pleased with the way it works. Thought I'd pass this along as a low-dollar way to install a starter relay and have an engine bump switch all-in-one.

painless makes some great stuff ;)
I have a start button in the blank to the right of the key, probably where the variable speed rear wiper control would be... very handy if you stall.

It would be nice to have a "bump switch" under the hood.

So this is inline to the S line to the starter? It looks like it doesn't switch the big battery cable a la a Ford starter solenoid.

Seems like it would be a good idea. Didn't the later B210s and B310s use something similar ("S" relay)?

Any old relay hooked up will save switches. Thats why you run a relay whenever you put spotties on so your 30yr+ wiring and switches that are only made to run about 1/2 the current, dont fry. It also gives full power to the item your powering(starter, lights etc) because your bye-passing all the resistance in the old wiring!

So you could probably make this setup for under 1/2 the price buying loacaly and seperatly!

A starter button under the bonet would be good though.

unless you have a habit of leaving it in gear after going for a drive. lol
And i'll just start her up so we can check the timing with my new bump switch thingamabob.....
duh duh aaaaahhhhhhhhhhhhhhhhhh my leg oh my god someone call an ambulance.
dont mind me im just a hopeless datsun freak.

That's correct. It gets it's 12v power from the battery cable at the starter. The piece in the kit with the two terminals is a circuit breaker that goes between the 12v wire from the relay to the starter.

I just have to be careful I don't drop a wrench on the starter switch when I am under the hood working on it

dude like beattie said 1 relay is all you need 5-10 and ure done i had the same trouble with my 120y
