My tacho has another red/green wire from its spade terminal to the 12 volt side of the voltage stabilizer and another is also soldered onto the ignition warning bulb holder. This is not shown in the workshop manual and I can only assume this is correct?
So do the joined wires (white wire bullets) from the tacho go to the negative side of the coil? The electronic dizzy has 2 wires Black& Red - that's all I've got.
Thanks again - I will get there
Kev.
The White wires should be removed from the back of the Tacho and joined together so it comes from the Ign switch and straight to the + of the Coil (not including the security switch if you still have it wired up)
A new wire is run from the -ve of the Coil to the Trigger connection of the Tacho
The 12v wire from the Stabilizer then goes to the Spade connector between the two bullet terminals that used to be the White wire terminals.
Don't forget to run a Ground to the Tacho body too.
You also need to determine which is the high voltage power trigger on the Tacho and the Calibration connection, on mine there not the same terminal.
https://www.spiyda.com/magento/index.php/tacho-wiring The RVC diagram second down, X is the new wire that needs too be added, pay no attention the how he's got the 12v coming off the Ignition switch on Elans it uses another Switched 12v (the Stabilizer power)
