    At this point I would suspect the meter fuses are blown! a quick check is to set the meter up for resistance reading, check that the shorted leads show ZERO ohms on the meter. Then take the red lead and check each of the two ports for measuring amps. they should show no more than .5 ohms each...

    Need advice on how to tackle an issue on my '86 305

    My tank does the exact same thing! Only difference is is does this on the tank that I am NOT running off of. Each tanks vent is sealed off when NOT in use and is vented when in use! Are you running dual tanks????

    If the battery terminal was welding HOT cut the cable back and install a New clamp on terminal. The weakest point in a circuit will become the hottest when attempting to draw a large amount of current through it. Check the voltage from the battery terminal to the rear of the alternator when...

    My 86 454 Conversion to Propane / Gasoline dual-fuel

    Looks great! Nice clean install! Back in the old days 1980's The City of Nashua NH was doing a test of alternate fuels for vehicles. My truck a Ford F250 was selected for the Propane conversion test. If I recall correctly the "Impco" injector was also used, the injectors were left in place with...

    Looking for 13.5v-13.8v voltage regulator

    The regulators in the 1 wire set up are the EXACT same regulators that are used in all other "same style" alternators. The difference is the external hook up to make it a 1 wire system. The standard regulators (2 wire) can be adjusted externally only to INCREASE the output voltage. This is...

    Quadrajet Spacers

    I mentioned the final solution to the problem in a fuel pump posting! The ultimate problem is not the heat but the excessive PSI provided by ALL the aftermarket pumps. My solution is to get a Holly F/p that is able to be dissembled (I don't remember the mod #) and REDUCE the operating PSI by...

    I had the same issue with getting a "GOOD" F/P that wouldn't flood out the engine every time I shut it off! After 5-6 years of dealing with WTF made in China junk the list of f/p's for different applications all ended up being the same piece of crap with a different name/model number on it...

    EXCESSIVE oil leak - Burning off exhaust, but from where?

    Do what you just checked for a pressurized crankcase! Any time I get a leaker to work on, I seal off all outside access from the crankcase then I use the oil dipstick tube to put the air hose to it! I use a regulator set at 5-10 psi max. Listen with a piece of hose for any/all hissing. check...

    Alt. signal wire

    From page #1 of the original problem: (Alt sense wire cooked) My first thought was that the voltage regulator was shot! As the "sense" wire does just that, sense the voltage of the "at use" voltage of the main electrical system in the truck. This wire only tells the regulator what the operating...
