Ok I figured out what goes to what sort of..
I checked 3 input to switch brown from fusible link to Am2 is 12 v...steady ok. But white was not clear at first I saw 12 v then I turned key to check one of its outs nada, but I lost 12 v in (white) AM1...

So currently on my way to work again. I think it has something to do of not getting 12v to arm 1. (wht).

According to the diagram it comes directly from a fusible link, (on the battery or somewhere else?

Start with checking the continuity of the fusible links, we need to know if they are OK.

I took off the connector and boot at the
+ term with the 3 FLs. Clipped on to connector and got continuity at each place they connect. They do not seem to want to unplug. also the visual looks ok..

I have put FusLinks back I am get a voltage +12 to arm2 but a drop at arm 1 (white wire from battery). I do not see anything between the switch and the fusLink.

Is there something that can cause the V to drop (getting about 9v) ...

Again thanks for your help, I guess I should start removing the wire shroud and see if there is a problem in the wires. Unless you think something else may be causing the drop

Try running a jump wire to see if things improve, if you head down the path of checking the loom check for any points that have a bend or are unsupported as this is where you may find a damaged wire.

Thanks, for your suggestions. I assume the loom is the serrated plastic that covers the wires. Are there points where I can jump as I found a wire diagram.

BUT it shows sw ------continue F Link --- Bat+
