'69 Camaro tacho
Just finishing wiring up my '69 Camaro & it's fitted with a factory tachometer. All of the wiring is as it should be, but when the ignition is turned on, the tacho bumps up to 1000 revs & stays there. There's no coil on it at the moment, but I'm fitting an MSD6AL to it. Is there anything else that needs to be wired in to make the MSD compatible with the factory tach & why does it jump to 1000rpm with the ignition turned on, thanks........Nigel
