Alternator tach failed

 Alternator Tachometer failed.

Our Alternator Tach failed on our trip out a couple of weekends ago. I guessed it was probably the wiring at the alternator. A quick look at the back of the alternator I could see that the white wire (tach) was broken. After removing the plug I also found the the sense wire (blue) was hanging on by a thread.

IMHO  - the wires from the Alternator plug are too short so the connections to those wires are subject to a lot of vibration strain.

We spent an entire afternoon searching local auto stores trying to find the standard auto part, eventually we found a store that had two. Looking at them both, one appeared to be defective, so I only purchased one. The wires are longer !!

It only took about 30 minutes to install the new plug and connect it to the engine harness. The new plug connector was $39.

With everything wired up, we did an engine check and all was fine. We're ready for our trip next weekend.

When I got home I did a search on Amazon for the connector. Most of the online auto supplies were the same cost. 

But this is for a Dorman 645-906 Blower Motor Resistor Pigtail $14.95 Same item!!!

Now I have a spare.

See you on the water.
