  1. I am working on a 67 beatle and it has no spark. Somebody may have wired this wrong and I do not know where the resister wire is. Could it be in the coil?

    • Hello, Monte…Could you send a message to my private e-address so that we can, for the time being, discuss this “off-line”? You can send your phone number, if you wish, if it wouldn’t cost you anything on your end. I have free long-distance. jay jksalservw@verizon.net

  2. Hello. I have a fully charged battery. All the outside lights are working..signals/highs/stoplights/hazards. Was losing battery voltage while car was on. As soon as I disconnect the neg. On battery voltage starts going up fast. Also after a while of being on if I turn it off it won’t start again. Lights dim and starter wont make any sounds. But battery reads over 12.5v. Whats going on ..??

    • Hello, Moses…..check the voltage from the generator with the car running (of course). It should be about 14 volts. Now, again with the car running, check the output past the regulator. At that point the reading should be 12 or less. Check the reading on the battery with the engine off. It should be stable with the engine off. Electrical can be stinky to diagnose sometimes. May your weekend go well! jay
