Thursday
I took a closer look at the ‘cooked’ alternator cable, the heat insulation was hiding a burnt inner plastic insulator. So I made a new cable and fitted it to the alternator in a direction opposite to the headers and leading between the alternator and the block.
Friday
Went to DMV with the brake & light inspection certificate. They gave me an extended permit through the end of August.
CHP called back – set up appointment for Tuesday morning.
Set up an appointment at Stone’s tires for Monday afternoon to do the wheel alignment.
Took Alex for a ride when it started cooling down (~6pm).
Alex on the way to Cisco Grove
Drove up donner pass on old highway 40. Must say this duratec engine has good low-end torque, 50mph in 4th all the way up. As expected the car sticks to the road like glue through the corners. We drove out to the end of highway 40 at Cisco grove, did a u-turn and came home. During the drive the speedometer started out regstering up to 50mph and being intermittant/failing above that, then got steadily worse until it could not register above 20mph.
Saturday
The speedo sensor was not centered on the toothed wheel (see photo).
Put in one washer, which gave better alignment. Adjusted the gap and tried the speedo, several times with different gaps, best was at 2.3mm where it would go up to 40mph, but started flickering over 50mph. Other gaps gave less performance.
Sunday
While adjusting, with the ignition on, the sensor has an led to help set up. I noticed that with the gap around 2.6mm, that most of the circumference the led blinked as I turned the hub, but about a 1/4 turn it was intermittant. Decided that it was best to exactly center the sensor, so added a second washer & set the gap at 1.8mm.
Took it for a test drive & the speedo was good through 55mph, then intermittant above.
I made static adjustments noting the led, at 1mm the led is on all the time while turning the hub. At 1.5mm, the led is mostly on with it blinking off when rotating. At 2.3mm the led is mostly off with it blinking on when rotating. Tried driving with these gaps:
1.8mm good up to 55 mph, intermittant above.
2.3mm good up to 20mph, intermittant above.
1.5mm good up to 55mph, intermittant above.
1.9mm good up to 58 mph, intermittant above.
I couldn’t get any better results
