you can't beat those old Ford solenoids. that's all we've run in race cars for years. i used to get them free at work, so pretty much everything i own has one

Speaking of solenoids, my argo's one was toast. I drilled the rivets out of it to see the guts.. it was pitiful how whimpy the internals were. I dug up a ford solenoid I had laying around for 20 years and bolted it on.

rectifier is the same as the voltage regulator i was talking about in your other post. your pic is of the solenoid. this is a like a relay. uses a small wire to control the function of a big wire. the small wire is sometimes called an exciter wire. it should have 12v only when the key is in the start position.

Ok, so i am confused a bit. I pulled up the wiring diagram for my attex and it mentions a rectifier. What exactly does a rectifier do?

A rectifier converts AC voltage to DC voltage or visa versa. It has nothing to do with your starting system. If the battery is holding aa charge, the (charging) system is working fine. What exactly is or is not happening with the starting system?

The thing in the second pic is the starter relay, a lesser charge from the key charges an electomagnet inside it making contact with the 2 heavy wires to engage the starter. If you jumper the little wire to the one coming from the batt it will click and the starter should work.

I think the 2 yellow wires are part of the charging circuit and the blue wire is a kill wire when grounded. (Guessing on second one )

Ok, so i am confused a bit. I pulled up the wiring diagram for my attex and it mentions a rectifier. What exactly does a rectifier do? I have attached a couple of pics of the wiring as i am trying to get the electric start to work. My shoulder just can't pull that rope hard enough. The three wires (2 yellow and one bluish green) coming from the back of the motor (see pics) where do these need to be connected to? One pic shows the wires on the back of the motor, the other shows something with mutliple wires running into it. Is this the rectifier or is this a relay? sorry, not to good with engine electrical items.
