    flex plate cover question

    in Drivetrain Tech

    Yeah, I thought they were 1/4-20 as well but a 1/4-20 bolt is too small in all of the holes in mine. 

    If it were just one of the holes I would think it was just worn out...but all of them? 

    Also, the 1/4-20 bolt is not just loose (like the threads were gone) but entirely too loose.

    Speedometer gear

    So I just bought another 70 SS454 which had the rear gears changed to 3:55s.  While I like this gear a lot for local cruising (and tire spinning of course) it is not so good on the freeway.  That said, I think I will leave it as is at least for now.  Can anyone tell me if I can simply change the speedo gear in the transmission to correct the speedometer...it is currently reading about 90 MPH when doing 70 on the freeway.

    While this physics lesson is very interesting I seriously doubt it has anything to do with my problem.  I seriously doubt the resistance change due to temperature would be significant enough in just a few minutes (less than 15) to go from absolutely nothing when turning the key to starting fine.

    Voltage drop is key. I have found that if you measure voltage at the violet color wire in the engine bay, while your fault is present. The wire going straight to the solenoid, after the NSS. You'll find out two things the voltage and wether it's originating after the neutral safety switch.

     

    If you have a strong 12v and the start sequence is not present, I'd say solenoid or stater related. Assuming good ground..if no or little voltage at wire, ign switch, NSS, or the old fusible link in engine bay. The key here once again is voltage drop.

     

    Doesn't the test I did of turning on the lights and attempting to start accomplish the voltage drop test you are talking about?  The idea is that if the starter/solenoid are getting power there should be a significant dimming of the lights when the ignition switch is turned to the start position.  If there is no dimming (which there was not) then there is no voltage drop.  Since there was no voltage drop I think it has to be either the ignition switch, NSS or the fusible link you mentioned but it just doesn't makes sense to me that any of those would be affected by the temperature of the car.

    So I had one of my cars out for what is likely the last time this year.  After driving some beautiful country roads for about an hour I stopped at a convenience store to get a drink.  When I got out of the store and went to start the car and leave, it would not start.  I turn the key but nothing happened and by nothing, I mean nothing...no click no nothing.  It was like the car was not in park so I shifted into gear then back to Park but still nothing.  I turned on the lights and had my wife watch them while I turned the key and they did not dim at all so the starter is obviously not being energized.  Sounds like the neutral safety switch but wait...

     

    This actually happened once before.  The car was hot after some long country road (read slowish) driving and I stopped at a friends house.  When I went to show him the car and start it up, same thing, no start.  I was planning to visit with my friend so I didn't worry much about it at the moment and figured we could look at it later when I was ready to leave.  When I came out some time later to leave the car started right up.  I ended up having the same luck this most recent time, after waiting a bit for the car to cool it started right up. 

     

    So the car acts like the neutral safety switch is bad when it is hot, but give it time to cool down and it starts right up.

     

    Can anyone suggest what might be going on?  Can the neutral safety switch be going bad in this way...affected by heat?

    1970 SS speedometer

    Well, dang ... my '70 SS speedometer only goes to 120 .. no wonder it is so easy to peg!  Guess everything is bigger and faster when you're bench racing!   :grin:

    Dennis - the new pictures of your cars in your signature look awesome.

    Steve Myrtle Beach is a long ways off from Hiwassee. I know I have been to both but not in the same year

    Yes, I know.  I have a very good friend who lives in Myrtle Beach that I was planning to take to the meet with me so I went there first to pick him up.  This friend and I grew up together and he and I owned the same Monte Carlo while in high school...we traded the car back and forth for about four years. 

     

    Anyway, despite not being geographically close, he and I have remained very close over the years.  Over the last couple of years my friend has developed a blood disease and is just generally in bad health.  I knew he would enjoy this meet as much as me so I wanted to take him with me. 

     

    The plan was to drive down to his place Tuesday, hang out with him and his wife for a couple days then drive on down to Hiawassee Thursday.  Unfortunately, as I said, I had some trouble with my truck.  It was nothing serious but I had to order a part to fix it and I did not get it until Friday afternoon so I was unable to make the second part of the trip.

    Radio Removal

    in Interior Tech

    Posted

    I know (from reading other posts) the radio (AM/FM 8-track) is only held in by the stem nuts and an 'L' bracket on the rear of the radio.  So the question is, can the radio be removed and replaced with out removing the dash?  If so can someone explain how it would be done.

     

    Thanks 

    Trunk and underhood lights

    Thanks everyone.

     

    The hood light issue turned out to be a blown fuse on both cars.  There is actually an inline fuse in the power wire which connects to the horn relay.  The trunk light in one car was just disconnected (not attached to the trunk) so it wasn't getting ground.  The other car just has a bad bulb in the trunk.
