ass relay 14.0
ignition relay 2. 0
ignition relay 1 0
ignition lockout 2 13.5 to 8.5

but with ignition lockout removed I had 8 volts on ignition 1 the one that I jumped, the reading dont seem correct so I'm taking my other volt meter and try again thanks brad

Voltmeters can really fool you. Finding a decent ground can be a problem. Based on the picture I suspect you have some large round binding posts outside of that nearby you can use for a ground.

I don't have time right this AM to search where your jumper is. That is, what is it bypassing,

Did you pull a relay from another spot to substitute in place of the one that is not working? You can chase your tail taking measurements but sometimes the best way is good old substitution.

yc1 yes I moved them around and even bought 2 new ones and replaced it I'm going to take a different volt meter over and check my readings thanks for the reply

First of all the by-pass wire you installed are for the fan. One terminal is 12v all the time and the other is going to the fan. Now the two connecter on the side are your control to put the relay on. One side should be 12v power and the other side ground, this is what puts your coil for the relay on. Now it's which one controls. Most of the time the power side 12v is the control wire. So a test light is the best to check this. If you have no power on one of the side connectors the power side 12v is the control which means one is ground all the time. So connect a test light or you ohm meter to a known 12v power source and check it see which one lights the test light. If the one that lights it means the other one is the power your looking for. You will have to find out where that wire goes. I usually goes to the switch that turns the fan on. When it's ground control it's usually the computer controlling it.
