Rev counter wiring

[lambrettalee]

i am fitting an after market TIM rev counter on my petrol caravelle, my question is , what fuse can i use for the "live when ignition is on" rather than running 2 wires to the coil, is there a spare or do i link to the cigarette light or something like that...

fag lighter is permanant live lee.

if you get the wire plug off the back of the ignition switch there is one there you can tap into.

aahh mine isnt , maybe its knacked, what about the indicator fuse or is that not a good idea, i dont want to cut anything about if i can help it,

pin 15 on the back of the fuseboard lots of spare ignition switched live outs, I haven't got a bordr to hand, it's the inside end of the board iirc

One of the relay sockets on the top row of a late van (no 2 I think) probubly has a rev signal going to it (should if your van has the buzzer of doom or rev counter), probubly a "15" pin too. Male blades will push streight into them without having to cut anything. You could take 15 off the back of the bord easy and tidy but a rev signal will likely involve tapping into wires. Remember if you don't have a rev counter dash you will still need a rev signal to it for the buzzer of doom to work properly (otherwise I don't think it'll ever moniter the higher running oil presure as it won't think the engine is running).

Ah, thats why the W connector is attached to a wire on my alternator - even though i havent got a rev counter?

So effectively, i shouldnt have to run any wires from the engine bay to get an aftermarket rev counter to work?

Sweet!

Thanks
