TR2/3/3A TR3A electrical issues

[Dave L]

To All,
I have two electrical issues I can't figure out:
1st issue: Horns
I wired up my horns yesterday and am still having issues, I had an issue with the contact on the horn button falling off and grounding out. I removed the horn button and fixed it and think I have them wired correctly.

D side​

NG wire to horn from harness​

NB to horn from 4 way connector.​

NB from steering column to 4 way connector.​

NB wire from main harness to 4 way connector.​

P side​

NG wire from harness to horn.​

NB wire form harness to horn.​

When I turned on the power to the car, the horns started blowing. I turned the power off and messed with the NB wires in the 4 way harness, turned power back on, now nothing?​

2nd issue: Headlights

Connected both blue/red and blue/white to harness.​

Turned on power and have 12v to blue/red circuit nothing to blue/white.​

I had a relay kit from Moss installed.​

I checked the voltage working back from the headlight buckets, no power to them, no power to them at the high beam switch, no power to them at the relay.​

I removed the relay and bench tested it, it tested ok.​

I replaced it with a new one and I still get no power to the wires?​

The car sounds like it needs a bearing in the water pump or alternator ,and the amp gauge pegs to the right when I pull the switch for the lights. when I shut them off, the gauge goes back to normal and the grinding noise under the hood goes away?​

I am at a loss as to what to do next.​

Any help would be greatly appreciated​

Thanks,​

Dave​

If it involves both horns, that narrows the problem to the wiring from the horn button to the driver's 4-way connector. So, the NB at the 4 way from the steering column should normally read battery voltage. Press the horn button to see if it goes to 0v. If not...then you have a button or steering harness problem. If it does, then the 4-way connector is at fault.

I am not familiar with the relay mod...but no power anywhere sounds like the power feed to the relay.

Thanks,
does it matter which way I plug in the NB wires in the 4 way connector?
