Hate being repetitive/redundant,

Get your mechanic to use a Non Destructive tone generator, connect to system side of F1 fuse, follow the tone , no need to open looms...

Guessing is only costing you $$$ and time...

x2,3,4. Frankly, it is the wiring, rather than the sensors themselves, that is much more problematic in these old cars. I wouldn't be really happy with a mechanic that hasn't taken the time to check the wiring with regard to a fuse blow, rather than 'diagnosing' sensors that, frankly, apparently weren't tested. Anyone can advise you to throw parts at the car in the hopes that you land on the right thing. While testing wiring (without a tone generator) may be a bit time consuming, it is really the only way to determine the problem. With a tone generator (and you can get an inexpensive one, as well), this becomes easier and, at least IMHAWO (meaning, in my humble and weird opinion)...fun.

In the '70's I used some equipment for finding wiring problems in aircraft. It was on a cart and cost a lot. I suspect you are talking about a modern version of this. It could be handy for both my Kicks and my motorhomes.

A Google search with your term I came up with some fairly expensive equipment that doesn't have anything to do with wires. Some variations of the terms bring up some electrical testing equipment but the prices vary quite a bit.

You wouldn't have a link to something that has the features useful for automotive use, but not cost an arm and a leg?

I have one similar to this http://www.ebay.ca/itm/Telephone-Ph...e-Tracer-Tracker-Tester-/310681465064?pt=LH_DefaultDomain_2&hash=item48560ef0e8, cheap, works and does not cost your arm or leg..

Son is an aeronautic engineer, he spent the A&L for his... but then I do not diagnose 747, 777, 787, Airbus, ect..

This has been discussed before. It is fine for telephone equipment and cabling but care needs to be exercised when using it on a vehicle with electronics plugged in - its more than capable of damaging an ECU.

I have used it safely, we are inducing 9vdc @250ma on a 12vdc >10amp circuit..
really no worse that using a DVOM, and much better than using a standard incandescent test light..

Its only a 10A circuit when its powered, injecting a 9V 250mA signal backwards into unpowered electronics can do a lot of damage.

Maybe we are rowing in a different life boat..

How does injecting 9vdc into a dead 12vdc circuit that has already suffered a blown fuse, differ than replacing the fuse (F1)..??

Any other circuit emanating from the ECU, would be already opened for testing (disconnected) from ECU.

LOL, if I'm not mistaken, which I often am, you have a naval background.

Is the 'AQUA'naut possibly a clue??

Just to add my 2 cents worth tothe discussion. About 18-20 months ago I kept blowing ign fuses as soon as I turned the key. After checking most of the wiring loom I found a short where the 2 wires going to the alternator ran under the the throttle body. I replaced and rerouted the wires and have not had any trouble since.

US or Cdn $$, yours could be a windfall.. That is a common area for abrasion..
