As stated in many "FLYERS" that are in the box of new/rebuilt STARTER....ALTERNATOR: "Disconnect the CABLE from where it goes to to TEST THE VOLTAGE at the end of that cable...it should be NO LOWER than .2 volts of the battery voltage. This is TRUE OF BOTH CABLES!

Should you replace this cable..... Rolling Eyes

probably!

What does it GROUND? The ENGINE/TRANS/STARTER....and the ALTERNATOR,(but only if the Alt. stationary bolt is paint/grease free) PERIOD! Rolling Eyes

Everything electrical was fine.....right-up-to when you wanted a HEAVY AMP LOAD (under differant temps) when you wanted to START THE ENGINE!

A new starter and a new positive cable.... Rolling Eyes

NO HELP AT ALL! Shocked

Now....because the POSITIVE SIGNALS...IS GREATLY REDUCED from the factory...INJECTORS...TPS...etc etc: Rolling Eyes

The BATTERY showed 12.5 volts....and after CLEANING of the NEGATIVE CABLE, it showed...12.5 volts. Meaning that, I do not need to REPLACE...that cable. Wink

Now....are you impressed with "NEW CONNECTORS"? Rolling Eyes

Better study those two terminal "W" crimps. Laughing

Ol' Mr. MOTOR MITE..YOU SUCK!

That WHITE wire is PREMIUM COPPER (Delphi)...without the MISS..of a SOUND "W" CRIMP....on the red wire, "MOTOR MOUTH" wire. Crying or Very Sad

"NEW" means ZIP...to *ME*...without the NAME! Rolling Eyes

Companies like.... Rolling Eyes

.....TEP (Top End Performance) Rolling Eyes

that would REMOVE THE FACTORY PACKAGE to HIDE THE TRUTH FROM *YOU*....KNOCK YOURSELF OUT! Laughing

Companies like: Professor Quest...BOSCH... MITSU...DELPHI...AC Delco....NIPPON...are NOT AFRAID to provide a SUPERIOR PART....for a couple bucks more! Wink

Noooooo, this is not a Starquest. Rolling Eyes

Buttt....I have a feeling that you own other vehicles....don't you. Cool

This complaint: Lost the lamp indication of "LOW FUEL". Which happens to be FAR....from WHERE it began in the BODY GROUND LOCATION. Rolling Eyes

Are these type of bolts "SPECIAL"? Yep! Wink

Bodys (from the factory) are PAINTED FIRST! This IS NOT SELF-TAPING......it IS....SELF-DE-PAINTING of the EXSISTING THREADS!

Boneyards have BILLIONS of CLEAN...USED ONES Exclamation

Sanding away the paint that comes into CONTACT with the SHEET METAL via the EYELET.....call it.... Rolling Eyes

TURBOCHARGED GROUNDS! Laughing

Complaints like: "My fuel gauge acts weird when the temps fall" or "I only loose instrument lamps when it's cold outside". And..."My cables/terminals LOOK clean enough".

Cure: Go buy an AIRLINE TICKET......cause *YOU*.....missed the boat. Laughing

CORROSION....is a BOAT-SLOW-LIKE PROCESS, and so is SERVICING THEM. Wink

That Mighty-Vac *ALSO* can generate vacuum if you are TESTING a vacuum servo, a Distributor Vacuum Advance Control etc etc.

Early ISC did not have a MPS. In 87-89 models they did (lil' black box) that has a SPRING ON TOP TO PRE-LOAD THE MPS....into the HOLDER-BRACKET.

The one on the right is not SPREAD... Shocked

WHY? Cause it fell outta place at the factory. Rolling Eyes

That SPRING is easily LOST........ Rolling Eyes

Above: You will FEEL...the PRE-LOAD of the stainless steel spring. Wink

Excuse me.... Rolling Eyes

Did you think you were being clever to take test inside that plastic housing,......ya lil' HACK! Evil or Very Mad

Note this: THREE WIRES IN....TURNS TO FOUR INSIDE THE HOUSING!!
The RED WIRE!! Rolling Eyes

You're exposed to PARTS CARS....of various makers....

...and it is SOOOO EASY to make your own test harness. Rolling Eyes

And you can use the "KISS" method....KEEP IT SIMPLE, STUPID! Laughing

3 wires to set the TPS...and 4 for the ISC/MPS, keeping in-mind that one one jumps to another inside the CONNECTOR. Rolling Eyes

The only use of the REMOVED ABS....is the MALE/FEMALE, ROUND FOUR PIN HARNESS CONNECTOR! Laughing

The "SAS Fixed" screw is what the DEAD-STOP...or REST POSITION for the butterfly is.

In the 88 factory service, pages 14-32 thru 14-35, is how you ADJUST your TPS.

As you can see...there is a bracket that blocks easy access to that screw
(in red) because...if you turn it, the TPS will need re-adjusted!

The instructions in those pages...are how to RETURN IT TO WHERE IT SHOULD BE! Shocked

Most of the used TBs I have come across are in a VIRGIN STATE and that's GOOD NEWS! Cool

The screw on the left is the ISC adjusting screw...and *YOU* are NEVER to back-it-out! It merely adjust the ISC STOPPER LEVER to MAKE SURE the ISC GROUNDS the ISC when it is returned to IDLE!

Any place you see a *DOT* indicates that SHIELDED GROUND WIRE is "Td" into that harness. Those lil' DASHES indicate that wire is SHIELDED GROUND.
CAUTION: A DOT in the DASH LINE indicates the shielded ground is sharded. But a DOT in the SIGNAL wire is sharded with another part.

Starquest with a A/T transmission using the 2 pin connector.
One terminal reports to the engine temp gauge in your dash. The other terminal reports to the A/T RELAY to let the relay know the engine is warm enough to use the OVERDRIVE!

If you have a 5 speed car.....ONE TERMINAL DOES NOTHING ON A 2 TERMINAL SENDER! Rolling Eyes

The 2 pin SENSOR is known to malfunction...and it might shift up-in & out
of overdrive but the OTHER pin reports ENGINE TEMP just fine. Rolling Eyes

YOU CAN...give that YELLOW/GREEN wire a FULL TIME GROUND and you'll OVERDRIVE command at the switch on your shifter handle. Wink
