Default Electrical problems with #782

Bob - I tried to send a PM on the issues below but it looks like it's not getting sent as it's not showing up in my sent items. Anyway, here it is in case my PM didn't get through.

I energized the electrical system in #782 for the first time today and I have a number of issues. Here are a few qualifiers in case they may be contributing:

- I unplugged my ballast resister to protect my distributor points from burning while I was testing.

- Brake system isn't filled with fluid.

- License plate light is not installed.

Problems I found are:

1. With battery hooked up but key off - the ignition light is on and the tail and parking lights are on. There is a slgiht discharge showing on the amp gage.

2. No turn signals

3. Heater runs full time with key in accessory or ignition position. I switched the leads on the switch without any change. I suspect the switch is bad.

4. No brake lights (possibly because the master cylinder doesn't have any fluid in it?)

5. Headlights, horn, wipers, dash lights and engine fan all seem OK. I didn't try spinning the starter since I had these other problems.

6. the right front park light would not light up at first. It had power to it but there isn't a ground in the harness for the housing. The black wire in the harness turns and runs to the headlight run and back up to the engine compartment. I ran a ground from the housing to the left light housing and it lit up. I don't know if that will interfer with the turn signals or not - I don't think so???

I double checks the wiring on the ignition switch and starter relay and everything is OK according to the manual and wiring diagram. I was careful wiring everything up. The ignition light/parking lights on with the key off is the issue of most concern immediately.

Thanks in advance for your help.

Dan
