First time poster...please be patient!
Some years ago I picked up a set of old gauges at a boat swap meet. Mostly Stewart Warner except the tach which is AC. I would like to install this tach when I get around to rebuilding the control panel on my 1964 Cheoy Lee Bermuda 30. I have researched wiring requirements on this forum and it looks straightforward enough. Problem is that the terminals on the tach are not marked. There is one insulated terminal right in the center with a white/black wire coming out, two other terminals towards the bottom (these may be part of the casing as they don't appear to be insulated) and then two other studs for mounting at the 3 & 9 o'clock positions.
Does anyone have the same tach? If so can you help me identify the wires please?
Other markings on the rear of the unit are : AC 8c , 12v., 27934, 6411529
I will try and add photos to this post.
Thanks for your help.
BTW...I have sweet-running 64 old style to which I have added electronic ignition and a late-model starter. One of these years I will bite the bullet and attempt a major rebuild. Compression is kinda low in the low 70s all along the cylinders but she runs well.
