I bought a 85 phazer le at the local grass drags , I put a new battery in it and the starter works fine . Problem I am having is when I connect the battery, the headlight lites up . This is with the key off. I cleaned grounds, switched ignition switches, soloinoids ,and checked all visible wireing etc. Any One have any idea where to look next/////??????????? THANX.

I think I'd start by making sure all the bullet connectors and switches are connected correctly. For the most part the colors should match up. I've got mine torn apart including the wiring harness maybe I'll look at it tonight and see if I can offer any help.
I have checked all visible and clean my grounds too. Could the starter be grounding out or the stator or small box electrical mounted on tunnel be of issue /////////?????when I connect the battery I iget a very slight tick-movement at the starter-or crank,but the starter is not engaged nor the key on .I have had alot of phazers and never had something like this before . Any help wood be great. thanks !!! Other thing weird is it starts and runs fine without battery connected .

You don't need the battery for it to run. I wonder if the starter solenoid is bad, maybe shorted to the ignition circuit sending voltage back to the ignition switch. Don't think I've ever seen one go bad that way but who knows. Try disconnecting the ignition wires from the solenoid and see what happens.

Time to get out the test light and find where batt voltage is getting into the light circuit.

I'm looking at the wiring diagram and the only routes I see for 12v to get back to the lights would be through the red wire with the fuse near the battery or the solenoid, although unless there is a weird short in the solenoid the 12v line to the started does not share circuits with anything else. So pull the fuse at the battery and see if that cuts the light.
If that cuts the light it points to a bad switch or improperly wired, but you said you changed the switch. Does anything else light up besides the headlight, like the tail light or speedo?

One other thought as I look at the schematic, check the rectifier, or unplug it. If it's shorted it can send battery voltage through the magneto.
I've very poorly colored the possible paths for battery juice to get to your light.
So to recap the 3 things I'd check to try to isolate the problem.
1. pull fuse at battery
2. disconnect red/white wire from solenoid.
3. disconnect rectifier.
Do one at a time and see if light goes off.

pull the magneto off. sounds like your charge coil and lighting coil wires have perhaps co-joined to one or the other from getting too hot or even a rectifier failure.
also be sure the wires are color for color in the connectors outside the mag and not reversed between white and yellow. yellow is your lighting, white is your output to be converted to dc power to charge the battery.
usually you will experience a fuse blow, but the wires being crossed or arced lighting things up may be diverting the power enough to avoid blowing the fuse.

thanx guys, will try tmoro
I believe I found my problem. Was the rectifier. I had a spare and it seemed to solve my problem . Thanks guys for your advice ,!

Awesome, glad you found it.
