Irish Mini Owners Club

Hi I have a smiths rev counter from a tripmh stag or dolomite. How do I get it to work on my mini

put it in ur mini hahahahaha - it wont work out on that thing you call a spare trolley

If its a stag its for an 8 cylinder so no good. There should be some writing on the front ie. 4cyl, RVI. and a number. Post a picture of the back of it. Are you running electronic ingnition( what type?)

Its not off a stag its off a dolomite i have the whole wooden dash from it . It has a spade connector and a push on connecter on the back im no good at putting pics up sorry i cannot do pics

There is an idiots guide to posting photos here,

wat u traying to say

i think you know dam rite wat hes saying hahaha

The bullet connector is the trigger wire that will run to the negitive side of the coil (white/black), the spade connector is the positive (switched) source so will connect to a switched 12v wire, and there should another spade connector on the case of the tacho, this is the earth. There should also be a buld holder as well, usually a single wire from that which will go to the dash lights, if double then one side is positive and one is earth, makes no diff which way round as its a bulb. Hope this helps

As GTM Coupe say's above, but no need for the earth for the rev counter itself as the coil it the triggering earth, the only earth required is the one for the light, which you would connect with the rest of your dash lights through the side light circuit of the mini as any of the normal dashes would be..

Simples...

Thats not entirely correct, its a miss conception that the "Coil -ve" is an earth or -ve feed, it is actually a +ve feed before the car is started and then switches on and off between +ve and -ve when started. Trust me I found this out due to not wiring mine up correctly on my current project ( got the switched 12v and the trigger wire round the wrong way, it worked but the needle would bounce up and down as the current was switched on and off, I checked with a multimeter and found the problem) Thus you do need an earth to the body of the tacho to get a correct reading and also the dash light.

Yahoo! Ot works thanks lads now were will i put it lol its a bit big lol
