Hello KR500, I would be thrilled to get an instruction sheet and schematic for my vintage Snap-On MT-640 coil & condenser tester. When were these built? Thank you, Kyle |

The bulb in mine broke in shipping and I haven't been able to find another, there was no number on it. Bob |

You can see the bulb in post #5 between the springs. Bob |

Re: Coil Tester needed Thank you KR500, Bob C and katy...
I'll start the hunt. When I bought it, without the bulb, I did use it too check my Model A coils and it did work. I think it's kind of a "buffer" for lack of a better word..for the bulb. djm |
Re: Coil Tester needed I was thinking maybe it would glow when there was power at the terminals
from the coil being tested so you don't touch them.:eek: Bob |

My Dad from about 1925 on to 1965 made a living as a mechanic. He built a test set of the day, to check current, and leakage current (with a milliamp meter, along with lights for just plain continuity testing and as you can see from the pic's also distributor points with a heater motor with a single lobe cam on the shaft, that speed could be adjusted with a rheostat as well as spark gap of the coil. The unit also worked to test condensers. Clever! Today ya just go buy one or more to do these chores.
