  1. The red inner fenders were used (but not always) in the GM A body cars with the top engine options....Like a W30.. 442 olds or a Ram Air GTO..Stage 1 GS Buick..Etc..
  2. Glad to here everything is working as it should..... The main battery terminal on the back of the alternator is supposed to be hot all the time and should show the same voltage as the battery even when everything is turned off...As that wire goes directly via a junction block with no interruption to the battery.....The diodes in the alternator act like a one way gate and they keep the battery power contained...from feeding back through the whole electrical system and killing the battery when everything is turned off.... The test you performed when you put the test light between the ground cable and the negative post on the battery is one way to confirm if the diodes in the alternator are working correctly and not backfeeding thru the system and killing the battery...had the light came on when you did that it would have indicated an unwanted power draw in the system ( like maybe the glove compartment light staying on all the time or something) and or a bad diode in the alternator..... On newer cars though...They are designed to have a very slight power draw....When everything is turned off....For the radio memory...Clock...PCM etc...
  3. It appears to me looking at the schematic that the F terminal on the regulator does connect to the F terminal on the alternator....The #3 terminal on the regulator runs through the ignition switch...and would be hot with the key turned on...The #4 terminal is used on cars with a radio.... A condenser is connected to #4 and is not used if there is no condenser.....this is the diagram hope you can see it clearly
  4. I Have an actual GM factory pontiac manual from 1963....(not a reprint) has at least 15 pages worth of info on how to trouble shoot ,test and repair the whole complete charging system...Adjust the voltage regulators Both types standard and transistorized voltage regulators...Complete wiring schematics.....Tried to take photos but they ain't coming out clear and legable with my phone..I have a way that I can scan the pages and send them directly to your Email..If that is something you would be interested in...
  5. Does your car have a standard voltage regulator or is it a transistor voltage regulator....
  6. Sounds like the battery may have a dead cell in it..When you put a multi meter on it...With nothing turned on does the battery show a 12 volt surface charge..?? Then with the multi meter still on it have someone turn the key to start the engine if the voltage drops way off...like maybe to 10.8 volts or less..That would indicate a dead cell or two in the battery.. I noticed that you said that according to the volt guage that it it showing almost 12 volts..If that is the case the alternator won't keep the battery charged enough to keep up with the electrical load and will slowly kill the battery...If the alternator is not putting out between 13.8 to 14.5 volts it will not keep the battery sufficiently charged...The easiest way to check is to get the engine running then take the multi meter and check the voltage right at the back of the alternator...Place the red lead on the big stud where the main battery wire hooks to the alternator then take the ground or black lead and ground it right to the case if it checks OK there..13.8 to 14.5 volts...any less it won't keep up...(Anymore than that indicates a voltage regulator problem)...If it checks within those parameters the the alternator is probably OK...One other check to do with the key off...Is to take a regular 12 volt test light...Pull the ground cable off the battery..Then put the test light between the ground cable and the negative post on the battery if the test light lights up... That shows that there is an unwanted power draw in the electrical system somewhere... Could also indicate a bad diode in the alternator... Next thing to do with the engine still running check the voltage right at the battery..If the voltage there is less than the alternator is putting out....look at your cables really close to be sure that they are not dirty at the connections or broken and is properly grounded (the heavier guage wire you use for the battery the better) ......
  7. Can't go wrong with the ceramic coating they look good...Plus the added benefit of....Cooler under hood temperature....
  8. Could very well be a wheel bearing...As far as low traction light I agree with Frosty and Last Indian..one of the wheel speed sensors..Unless there is something obvious you will have to hit it with a scanner to tell which wheel it is...
  9. Are you sure it is a bearing..?? And not a bent or flat spotted wheel or something along those lines..Is there any unusual grinding or roaring noise when driving straight or rounding curves ETC....??
  10. Beautiful car...The Silver and Black is a really stunning color combination......
  11. If you're having a hard time locating the wiper motor assembly....Or would like to keep the original...It is a serviceable unit and can be repaired...took photos with my phone hope you can see them OK...Hopefully this helps....
  12. Wrongway Could you tell if the idler pulley is turning..?? Or am I just old and blind..???
  13. Looks like the tensioner pulley is the one making the noise..I Couldn't really tell but at about 46 seconds there was a brief shot of one of other pulleys not turning...??? Lower right hand side...or am I just crazy .....Won't let me replay without starting completely over.....looked at again Is the pulley on the far right turning...Grooved idler pulley maybe...????? Can't really tell...
  14. Am assuming the car is equipped with the Super Hydra-Matic transmission..?? Also is the car column shift or floor shift...?? On column shift cars the neutralizer switch is non adjustable.... But it is adjustable on floor shift cars..If has floor shift it's very possible that it has slipped out of ajustment... If the car is equipped with the Roto Hydramatic (AKA Slim jim) the procedure is the same...
  15. Agree with Wrongway and Frosty... under dash left side...Might also have to remove a small plastic panel at the very bottom of the dashboard (should be marked fuse panel access)... Will more than likely have plastic fasteners with a slot that is large enough to use a penny or a dime in lieu of a screwdriver to remove them... Under the steering column or just to the left of it... To be able to see and access it....Will probably have to crawl under there on your back to be able to get your head in there far enough to be able to see...
