    How to wire dual alternators.

    The OEM dash alternator or battery symbol on the dash is a 194 peanut bulb. In the schematics it has B+ from the key during crank and run. It goes to the bulb and the to the exciter terminal of the voltage regulator. The bulb acts as a current limiting device and allows only 0.25 amps to pass...

    Alternator good but not charging battery

    GM schematics show terminal direction. Arrow pointing out is a male pin. Arrow pointing in, is female connection. Also, the 194 peanut bulb allows B+ thru it to excite the alternator, but acts as the current limiting device. A hot bulb, when on has high resistance. While voltage remains...

    Fuel Pump Hanger, '97

    Attach photo of what you need. I have 38 pumps in box and 58 single pumps alone. Most are all plastic bucket type w/pump inside & sender on the side. Have to dig but all inside garage, but need photo of part either off truck or internet screen capture! Best of luck!

    Voltage drop diagnosis

    A voltage drop of 10Vdc on the negative side from the new battery to block, leaves your starter solenoid with 2.8Vdc (12.8V - 10.0V = 2.8) Use a good jumper cable from battery to starter at bracket or other good ground. If it cranks hot or cold, paint, loose bolts, loose ground wire to block or...

    I think I have water in the fuel

    If this distributor there is a fin or fan shape on the bottom of the rotor. If yours has this, it means that there is a screen in the bottom. If plugged, it builds up with oxygen ozone and creates an acidic coating on the rotor terminals, cap terminals even the connector to the ignition module...

    I think I have water in the fuel

    Don’t forget that warmed up engine is running the purge valve to evacuate the activated carbon canister all the time. On or off as later models use PWM. So water can come in thru tank valve, rust vent tube all behind the left rear wheel. A brilliant place to put everything as if in the engine...

    Caliper rebuild--iron single-piston

    I get most of my parts from Rock Auto and Taiwan has become the big player in new castings with steel pistons. I have been rebuilding calipers since the 70’s. Had a hay day when Chrysler moved to “Phenolic” pistons. They swell and stick and great for business. But I would rebuild a caliper every...

    98 c1500 lopes like a dragster.

    Find the EGR. No mention of temperature at startup. They used a VSV the size of a pack of smokes. They get moisture in the lines or vacuum switch valve. It blocks, freezes and holds the EGR on. Use gloves or shop rag, find a position to put one finger on the diaphragm. No EGR at idle, cold or...

    Rust in thermostat housing

    Just soak it in a 5 gallon bucket filled with “Muratic Acid” sold a home improvement stores for $7-12 per gallon. As a device manager at a boat dealer and service center for boats to 34’ twin engine, this is salt water damage, not river or lake water. Muratic acid is the same cleaner used on...

    Big 3 cable upgrade crashes into ohm's law

    There is no reason to go big unless needed. Being man made, nothing is perfect. I chose to test a circuit with voltage drop. A terminal, fuse or switch will have voltage drop. A little is acceptable as using “Ohms Law” the sum total adds up to be more than the supply. I did not read about...

    TBI gas tank in Vortec truck?

    Check online at Rock Auto to find tank, pump and engine combinations. Spectrum is the largest supplier of senders and tanks. Pumps made for the correct engine be it TBI or 52 PSI LS engines. Bucket types have two filter and bottom mounted. One filter outside say 50 microns, but inside on the...

    TBI gas tank in Vortec truck?

    To andy396 1995 was a year the “Bucket” style fuel pump came. The worst thing is to aerate fuel, dropping volume and resulting in a lean misfire. At CARB and GM + others, they screamed! The fuel pump in a bucket uses high pressure fuel in a “Tee” fitting just above the pump. If this is what you...

    73 & up engine shells to fit clamshell motor mounts

    I prefer the clamshell rubber/steel motor mounts for safety, but I am needing the stamped steel 3 hole shell that sides over them, called mount shell, shackle or bracket. eBay sells these but are too narrow for metal to metal engine mount. This has to work softer so my wife will drive it...

    Fuel pump snap ring problems.

    I am glad the vehicle has been identified. Information, rather than insults from the few, knowing what vehicle we are talking about is more helpful to fix a problem.

    Fuel pump snap ring problems.

    Did know you had no control of your emotions! Have your bitting your finger nail or have you tried depends? My grandma used them. What is your problem? Are you honestly that mad at someone trying to help? Seriously? Do you shoot your neighbors dog or just poison it? I am going by what I have...

    Fuel pump snap ring problems.

    Wow, Have never seen an actual snap ring to hold a GM fuel pump in place...ever! What does RockAuto show in listing for fuel pump retainer? Still waiting for "This" answer!!! Pump fell inside? Right tank? Right Pump? Not supposed to be Snap Ring?

    Battery keeps being drained

    Use your test light or DMM to ground, then positive lead to anything that is normally hot, from Cig lighter, turn signal connector at bottom of steering column. If I have $2k sitting around, I might even use "Thermal Imaging". But then you would have to pay a co-pay and have an appointment. :)

    Battery keeps being drained

    Good catch on the oil pressure as GM used it to "Kill" the fuel pump circuit if you found yourself upside down or in an accident. Great Job to "Both" who posted about bad diodes in the alternator. I have seen this before many times. Positive diode shorts to ground, Negative diode shorts to...

    Fuel pump snap ring problems.

    These are bottom referencing modular fuel pump assemblies. You have 3 springs pushing the pumps bucket to seat on the bottom while sitting on rubber feet, so there is going to be a strategy for the install. While the dealer uses a spanner socket the fits the retaining ring, you don't have...

    I need AC! Help!

    What is going on here? Seriously, the A/C works, hand get cold on low pressure line while operating? Dude says to bend & epoxy? WTH. Blend doors move to direct air thru the heater core or around it, so hot or cold, not floor to feet. You are not removing the "Whole" dash, but you do have to...

    I need AC! Help!

    After research in my area, Advanced Auto sells "Interdynamics" A/C Pro universal leak dye for R12 / R143a UV in 1 oz bottle. This will do 4 vehicles as 1/4 oz is required. The bottle is marked on the side so add into a low pressure hose disconnected or into the accumulator. Take your R134a...

    285s - MPG dropped... Normal?

    The 285 is width of the tires tread in mm, while the second number is 75. This is 75% tall as they are wide. This 75 changes the overall circumference that effects the number to rotations per mile, so less. The transmission will shift differently due to TPS, Timing, RPM, VSS and knock sensor...
