Quick test for oil pressure switch?
What's the procedure for checking the oil pressure switch while it's in the car (with a multimeter)?
Dash light is flashing, but handbrake checks out ok from quick inspection. I'd rather not have to strip that down to diagnose. Proper oil pressure on gauge still there. Thanks ------------------ '72 911 TE |

Matt,
With the motor *off*, you should have continuity. With motor running (and oil pressure), the switch would be *open*. Keep the meter out of the fan :0 ------------------ '81 SC Coupe (aka: "Blue Bomber") Canada West Region PCA The Blue Bomber's Website |

Ya' know, this is *no* joke.
A fellow in our club was checking the dipstick with motor running. He wiped the stick with a rag, and absently-minded laid the rag down on top of the airbox. I don't have to tell you what happened next. He had to remove the top of the motor to get all the bits of rag picked out  ------------------ '81 SC Coupe (aka: "Blue Bomber") Canada West Region PCA The Blue Bomber's Website |

Good advice. Now you've all got me worried though. Should I be wearing thick rubber gloves and boots and an earthing strap round my waist before I attatch the meter to the pressure switch?
 Just kidding. I agree, safety is so important when working on cars. Fortunately the institute I work for has filled our heads so full of Health and Safety legislation and training I now feel invincible. Is it the same in the US? Our buisnesses get hit really hard if any of the employees have preventable accidents in the workplace, so they invest huge resources into staff training. That's good for me because I get to do some cool stuff and the certificates to prove it, but sometimes it verges on the ridiculous.... |

In my youth (long ago), I neglected to remove my watch when working on a car. The metal watch band briefly contacted a hot terminal to ground. The resultant high current flow promptly burned me (how fast can you take off a red not watch band? Answer: Not fast enough).
It was a mechanical watch so the only damage was to the epedermis. I suppose that's why so many electronic watches have plastic wrist bands; not to prevent personal injury necessarily, but to protect the timepiece's electronic circuit. :-) Sherwood Lee http://members.rennlist.org/911pcars |
