Hi All,
I`m having problems getting my tach to work ! It`s a RVI 2430/00 on a neg earth TF . I`ve decided to rewire it as existing wires are not working & colour coding bares no resemblance to the MGB loom . So can anyone tell me what wire goes where on the tach & from where it comes ? The connections on rear are a group of a female & male bullet connector & a spade. Am i right in thinking an earth is taken from mounting posts ?
Any help would be much appreciated.
Thanks John

This is the bible for all matters mgb http://www.mgb-stuff.org.uk/electricstext2.htm#tach Hopefully you can work it out from that.

Goood luck
