Electrical

 Have installed original Porsche Cruise control using all original components from yes, a wrecking yard. All components including wiring harnss all passed our visual and electrical testing. We tested harness from main relay/module to clutch switch prior to install. We had to make our own harness from pedal switches to back service and throttle switch, not an issue.

We strive to installed said conponents exactly like Porsche intended and this install was installed as such. Eveything in place like the factory would have installed. Process took almost 10 hrs to do.

Suggestions to upgrade my very poor headlights They are original  car is Euro spec car.

Hello, I am looking for help in identifing what these items are and if they might have anything to do with my CD box not working?

I have a MSD sytem with Blaster coil new wires plugs cap and rotor. Late last year lost spark. Spark out of coil is strong but no spark out of no one of the cap. What should I look for? 

Thanks,

1979 911sc after evaluation of non-charging issue, replaced original  external voltage regulator & Marchal alternator  with new Bosch external regulated unit, car holds a charge great ,charging 13 volts at idle. Problem with alternator light, when you start the car it goes on, after a few minutes at idle goes out, but when you rev the car light gets brighter as the revs go up. Any ideas? Thank you TonyG

I just purchased a 1983SC and have the following problem.  While traveling if I turn on the lights the speedometer drops by approximatley 15 mph.  Any thoughts as to what might be going on?

82 911SC.  Was having an intermittant starting problem, but now will not start at all. Turn the key, and all guages light up, seat belt buzzer buzzes, and all accessories work. Used to be able to turn the key several times, then it would crank & start. New High Torque starter installed approx 2 yrs ago. Just replaced the electrical portion of the ignition switch, and still nothing. Tried turning the ignition switch with a screwdriver, to rule out the mechanical part of the ignition switch. Still did not crank.

After I use the turn signal the high beams come on and the problem has gotten progressively worse so that I now have to jiggle the lever and it is difficult to get the high beams off. Is the turn signal and the high beam switch combined?

I upgraded to the H4 100/80W Headlights 30 years ago and the bulb just exploded. It is very cloudy inside of the headlamp unit. Can it be cleaned? What is the best way to clean the inside of the headlamp unit or do I need to replace the entire unit or worse yet both sides so they match.

Had my alt rebuilt and after removing the radio suppressors and grounding the double brown wires to the engine case things worked for a while. Went for a test drive after start/stopping the engine 5-6 times with all operations normal. Alt is Producing approx 14v at idle. when I turn key off the red alt light comes on & stays on. What should I look at?
