Topic: Why can't I get a reading on my old Lawrence 705? |

For a change, I pulled the old 705's out of my Super Pro that I installed 25-some years ago and put the original Sho-Bud pickups back in. After removal, I put a meter on one of the 705's and it gave a good reading but the other one I couldn't get a reading. I checked and doubled checked the wire and it's OK. I hooked the pickup to an amp and there is strong output from it.
But I still can't get a reading on it. Why? |

Something in your signal chain is intermittent. If you keep trying you will eventually get a reading, or discover that you have a bad pickup  |

| Ina one year period in the shop I had a Barcus Berry steel pickup, a MSA Super Sustain and a 69 Esquire all the same. Strong, but very trebly output. All had open coils and needed replacing. |

Connect a capacitor meter across the pick-up, just like an ohm meter. If you have an open, it will read some value of capacitance. If the pickup is not open, the meter will show an error.
The broken windings or connection wires of the pick-up will form a capacitor and allow audio to pass to the amp. Although, it normally is higher frequencies. The cap meter can read this capacitance.
