Okay
I have a 65 Falcon/Ranchero
I have recently rewired the whole car (not my first rodeo), using
a GM based harness kit
Added the GM bulkhead---and dealt with Ford's silly headlight switch
If any of you have ever looked at the FOMOCO ignition switches of yesteryear,
you can see how one would be very leary about upgrading an electrical system
and using the available switches and pigtails (looks like 16ga wire--maybe a 14ga feed)
So---I wire in a couple of relays----one for the ignition buss and one for the ACCY buss.
The ignition buss is powered thru the relay AND gets juice from the ignition switch (car keeps running in the event of relay failure.
Accy buss is powered solely by the relay
Today---I thought I would power up a couple of circuits
Circuits I wanted to test were good---AC, Stereo, dash lights,
Only put fuses in the circuits I was playing with.
Turn key off-----everything on the ACCY buss shuts off, but the ignition buss is still hot.
(While I was pondering this, my son called to come and get him as his car decided to not start on the opposite side of town)
With the key off-----oil and ALT lights still on---power to the wipers.
Did not really check the fuel gauge but should have.
Disconnect battery---everything dead----hook up battery----everything dead. Turn key on, everything fires up----turn key off, radio is off AC is dead
but still have dash power.
Is it possible for an ignition switch to do this?? It is the original and has been in a box for over a year not getting exercised.
Will probably get a new switch tomorrow after dealing with the offspring's car. (Towing involved---day off work involved)
Anyway---here is a diagram of how I have this thing wired---can you have a look and see if I overlooked anything?
