I had a dead battery in my car yesterday, I jumped it and went on my way. After a 15 mile drive the battery was still dead and I had to jump the car again. I borrowed a battery from a friend and put mine on the charger.
And now I am wondering why my batter was dead. I disconnected the radio and with the car/ignition/lights/etc. off I put my Amp meter in line between the battery and the + cable an found that I have a 0.60 Amp draw on the battery. Are there any usual suspects that may cause this drain on the battery? The car is a 1970 with a 2056 D-jet. |

so I have traced a short to the ignition switch using my Ohm meter.
The funny thing is I only have the short when the key is in the off position. When I go igniton "on" the short goes away so I am guessing my switch has failed. Any thought from the World? unfortunately I had a minor surgery on my foot and need to spend most of the weekend with my foot elevated so I can't do much more work today. Although I would argue that being crammed with my head under the dash most certainly keeps my foot elevated!! |
