Why would you want to operate it at 16” hg and lower? I operate mine at higher than that and I am located at over 5000 feet elevation. Emery Stora > > Rob, > > Please do. I am persuaded my current auxiliary pump isn't working and I was > out of the loop when people bought up the Azure...

Tom For several years I towed a Keep CJ7 across the country with my 3:07 final drive. I then determined that my wife’s Jeep Grand Cherokee weighed about 400 pounds less so I started towing that. We never had a problem with the 3:07. I later put in a 3:55 and bought a geo Tracker. Emery Stora...

The sense wire to the alternator does not connect to the isolator. It goes to the engine battery through the wiring harness. If the isolator failed it shouldn’t drop the sense circuit. When your isolator failed it didn’t allow the alternator to direct the right voltage to the engine battery...

But Ken — Even with an isolator "the chassis battery is always connected to the voltage sense line to the alternator”. I would think that if you have a combiner then the voltage sense line is connected to both the chassis battery and the house battery which would then “hide” a weak chassis...

Tom Glad to hear that you have it working. As your batteries charge up the voltage should drop a bit. Emery Stora 77 Kingsley Frederick, CO > >>> The sensing wire from the alternator that controls the internal voltage regulator goes to the engine battery. >>> >>> If the 11.8 volts he...

The sensing wire from the alternator that controls the internal voltage regulator goes to the engine battery. If the 11.8 volts he mentions is the engine battery it could mean that the isolator is indeed bad and the low voltage it is providing to that battery is causing the voltage regulator...

Shut it down! Way to high voltage on the bottom! You’ll ruin your batttery. Yes, it looks like a bad isolator. Emery Stora 77 Kingsley Frederick, CO > >>>> Do you have a hand held voltmeter? If so, I'd check the voltage across the battery and the voltage at the center position of the...

Tom The DL7157 is what I user. You should note that it is not the original 80 amp alternator. It is a 100 amp alternator. Emery Stora 77 Kingsley Frederick, CO > >> I searched Autozone for 77 Toranado alternator and I want to make sure. > > > > we lost our alternator on during our last...

They did not have a 455 engine in a Tornado in 1977. When you ask for engine parts you should ask fo 1975. They made some minor changes in 1976. Emery Stora 77 Kingsley Frederick, CO > >> I searched Autozone for 77 Toranado alternator and I want to make sure. > > > > we lost our...

Sorry, that was a 1993 Jeep Grand Cherokee but that’s still 22 years and 300,000 miles of usage on the original in-tank fuel pump. The eight year old ones in my GMC now have about 130,000 miles on them. Emery Stora > > True, but how often are you planning to replace them? > > Mine have...

True, but how often are you planning to replace them? Mine have been in for 8 years now and are still working fine. If one were to fail then I still have the other — or if I didn’t have the time to replace an in-tank one I could always hook up an outside the tank one temporarily. The in-tank...

If you have chips that have flaked off then it definitely isn’t the original. The original pant was Imron, a polyurethane paint that won’t flake. Emery Stora 77 Kingsley Frederick, CO > > Thanks everyone, as usual, for the advice and help via the forum (and email). So it looks like my next...

I bought one of the filters that Bob makes to fit the GMC while at the Elkhart rally in Indiana. It was designed for large trucks operated in dusty conditions. Very easy to install. Emery Stora > > I use, and love K &N filters on my road race track cars. But never on any street cars, or my...

Yes, I am aware of that. A generator puts out DC while an alternator puts out AC. Our alternators make ac but it is internally voltage regulated and inverted to output DC. Emery Stora > > Emery, > > They called it a generator because that's what it does. AND also because Chrysler made the...

That’s all right. GMC also calls an alternator a generator or motor generator. Just look it up on out parts book or maintenance manual. Emery Stora > > They couldn't agree whether it to call it a "dampener" or "damper", so they > compromised on a word they could all agree was wrong...

According to plug information I have the R46SZ replaced the R46SX. The SX's were gapped for .080 and the SZ was gapped at .060. Only difference. Just bend your tab on an SX and make it work. However the current thinking is that a .038 gas is better with the hei system. Emery Stora > > When...

The nylon gear is made of self lubricating nylon. It will wear much less than steel or aluminum. If you were to substitute a metal gear it would likely fail soon. Emery Stora 77 Kingsley Frederick, CO > > Ill be the first to admit I carry a spare governor gear with me just in case. But would...

Yes, you definitely need the brace. Otherwise you eventually will stress crack the metal where the booster is mounted. Emery Stora > > The top nut on the passenger side requires the use of a wide range of cuss words, especially getting the washers back in place and the nut started on > the...
