white to white without the tach in the loop no change from yesterday.
back to "normal" white ignition wire to coil Pos, car starts and shuts off no problem,
and white/black striped wire from tach to Pos of coil.
There are some issues here. Let's address them in reverse order.
There MAY be a white/black wire that goes from coil (-) to the distributor. Though a white/black wire is used with the later RVC tachs... there should
NOT be a white/black wire going to an RVI tach. If you have a white/black wire going to your RVI tach... remove it and tape it off. More info on RVI tach wiring below.
I don't know how many white wires there will be on your particular installation. In Lucas wiring codes, white is "switched" and "unfused". All original/factory white wires should be "hot" with the key in the run position.
You listed some of the tach wiring in your first post. Based on your statement in the post above about a white/black wire on the tach I want to clarify the RVI tach wiring. Forgive me if this is what you already have but I want to make sure we are talking about the same connections.
For an RVI tach there should be...
First white wire from the ignition switch to a bullet connector on the back of the tach.
Second white wire from the remaining tach bullet connector to coil (+).
Green wire (switched and fused) to the spade lug on the back of the tachometer. This will be the spade lug next to the bullet connectors. It is on an insulator plate and should not be confused with the ground connection spade lug sometimes spotwelded to the gauge case.
Black ground/earth wire connected between the tachometer case and the car's chassis ground.
(Some gauges use a spade lug spot welded to the gauge case for ground. Others use a ring terminal placed over a gauge mounting stud for the ground connection. Regardless, make sure the tach has a ground).
White/black wire from coil (-) to the points connection on the distributor. (NOT part of the RVI tach circuit.)
