Need a solution for stalling problem
OK, here's the typical scenario: I'm riding down the road in my '67 L71 minding my own business; a split second hesitation is felt/heard; about 15-30 sec later an earth-shaking BANG (? back-fire) is experienced and within 30 seconds the car dies and won't restart. Turns over with no spark.I open the hood, jiggle the TI connector behind the driver's side headlight. Car will immediately restart as if nothin's wrong.I've tried coupling grease in the connector and it helped for a while but problem has now returned.Is there a new connector I should buy. Couldn't find one during a search of usual suppliers. Is there another solution?Any suggestions appreciated. Thanks!Ron

Ronald,
Get a ohm meter and check the ground wires to make sure the amp is grounded to the core support. -
Re: Need a solution for stalling problem
OK. Thanks. I'll try this. Do I need to test this while in "stalled" state or during normal operation? Would it make a difference?Comment

Had similar problem T.I. amp /amp plug /and harness were the problem. 66 L72Comment

Re: Need a solution for stalling problem
Ron,
If it's a poor ground connection, you should be able to duplicate the problem in your garage without running the engine. Just wiggle the ground wire while watching the Ohmmeter to see if you have an intermittent connection. You may need to clean up some rust under the connection or perhaps it's a bad crimp or something.

Thanks! Any chance a photo could be posted of exactly where this ground wire is?Comment

Re: Need a solution for stalling problem
Ronald,
If the amplifier is mounted on the inner fender there is a ground wire that grounds it to the core support. If it's mounted to the core support the ground path is through the core support but you have to start by making sure the core support has a good ground to the frame.
Did you remove the amp and check the condition of the terminals for corrosion.Comment

Re: Need a solution for stalling problem
Tim, the unit and the wiring harness are both new. The car recently underwent a complete nut and bolt restoration. The amp is mounted behind the headlight. I'll take a look closer when I get back from spring break. The core support is where the radiator is mounted, right? (I'm like a babe in the woods here, but I'm learning slowly.)Thanks for your patience with me.Comment

Re: Need a solution for stalling problem
What is "coupling grease"? You may be making the problem worse if that product is not designed for electrical contacts.
If you have a new TI harness and the TI module is the new type(or original type), it's possible the ground is the culprit, but as mentioned, the 3 male terminals of the module circuit board to the female wire terminals, then the 3 female terminals in the rubber connector, which the TI harness connects to, may be intermittent as well. (see pictures..... worth all of those words
)

The ground for the module attaches to the rad support frame as seen below. Yes, as mentioned, verify continuity using a ohmmeter from engine ground, to rad support, to TI module case. Note, not just the 1/4" mount bolt.....at the mount screws for the rubber connector housing.

Also note, that ground at the case isn't necessarily a guarantee that the circuit board is grounded. The screws mounting the circuit board to the module require a solid physical contact to the case, with internally serrated washers under the screws to ensure good contact, as seen in the 1st pic above.
I would take everything apart and do a 100% check of all of the pieces of the puzzle, and I would clean out all of that grease and leave it dry. The rubber connectors seal out moisture by design. I would give every male connector a cleaning, and give s slight "squeeze" to every female terminal to guarantee proper contact.

Tim, 4 days in Jamaica . I need it badly after this past winter.
Rich, thanks a bunch! I'll be going after this as soon as I return.ill let you know how it goes.Comment

Re: Need a solution for stalling problem
OK, I'm back now. Took her out for a spin today and didn't go 5 min when it stalled as expected. This time I just wiggled the ground wire where it attaches to the connector, not the whole connector plug, and she started right up. The ground attaches firmly to the core support and looks clean. Here are pics of the area. I will get an Ohmmeter tomorrow to start checking for bad connection.Comment

Re: Need a solution for stalling problem
UPDATE: I loosened, then retightened the ground wire screw where it attached to the core support. Took her for a spin. Went 20 minutes with no stalling. First time that's happened for over a year now. I'll repeat tomorrow to verify.Comment
