Hey Tim 

Thanks for the comments;

Well, we are the second owner of our car, and I personally tore it down for the project rebuild, there was no evidence of a floor mounted starter button so I am not really sure what the original design was, furthermore it is not covered very well in my shop manual, regardless, it is not the issue here.  Having a 12 Volt solenoid mounted to a starter motor that was wound for 6 Volts is the issue, and in my humble opinion not very reliable for the long term.  Hence the reason why I want reference to a newer 12 Volt set up. 

By the way , I don't have to design or fabricate anything, it is already available through a company called SNAP Rebuilders located in Utah USA,  I was only looking for a Canadian supplier of the same type of starter to help make the purchase more economical. 

Thanks for the comment.

Hey Tim

Yup, my problem is pretty odd to say the least, Wednesday,   I pulled the starter from the car and placed it in a vice so as to just hold it.  Thursday ,  my buddy and I used a set of booster cables from a fully charged 12 V battery and connected the solenoid Positive and then the negative clamp to the flange of the starter.  I then used a inline 25 amp fused wire and engaged the solenoid.  The starter turn and appeared to work fine. ????????

I then went back to the car with the goal of confirming the ignition switch as being OK.  So I attached the main 12 Volt wires near the starter location, wrapping with electrical tape,  keeping the ignition wire separate. I then connected the positive on the battery terminal and then the ground.  My buddy held the  test light on the ignition wire and clamped  the alligator clip to a ground , then I entered the car and turned the ignition switch to start, The test light came on , so it appears my ignition is OK. 

Really not sure what the issue really is??????

In closing, I placed the order for the new Mini High Torque 12 Volt starter

Things That I will work on to improve reliability :

• Installing a independent ground wire instead of relying on the bolts to serve as the ground connection.  
• Installing a second line from the starter/solenoid  12 Volt + up to the push button and removing the existing Solenoid wire from  the ignition switch and connecting to the push button , of course the line will have a inline fuse .  

Tim if you want to see the original starter c/w solenoid you can see it in the CP Feature Cars folder August 2020, I have pictures of the original starter and also of the new 12 Volt solenoid / 6 volt starter motor. 

Thanks again Dale 

Hi Carl

Thanks for the input, I can & will do both of your suggestions.

The car has no fire wall plug or recepticle, my solenoid lead wire is direct from the ignition switch , which as mention,  lit the test light when turned to CRANK.  For this test, should I keep the starter connected and have it turn, if it will , which I suspect it will with a temporary ground wire,  while I check the voltage ?

Hi  Carl

Well I was intrigued by your comments, so I went right down to the Pontiac after reading your comments and began the tests.

I connected the high heavy gauge 12 V positive wire from the battery and the leads to the fuse panel. (bolt and Nut with tape )  No starter in line at this test point.

I then Checked the Voltage at the battery , 12.7 Volts . Connected both Positive and Negative leads to the battery, which I thought were good connections, Hmmmmmm ,

Then I checked the 12 Volt Positive connection which were taped , 12.7 volts. no losses at this point. 

I had my wife sit in the car and turn the Key to the CRANK position ( Nothing ) Then I noticed the dome light was not lit and her door was open ?????? 

I then Checked the 12 Volt positive wires at the taped location with a test light (Solenoid location ) Nothing. 

Went back to the battery and gave the negative 1/2" nut another turn  and the dome light came on. 

Rechecked the ignition lead to the solenoid voila 12.3 Volts. 

Lesson learned my negative ground clamp is not adequate and needs to be replaced.  ( it's original )

Tomorrow I will install the original starter ( not connected to the motor) and terminate the electrical connections and repeat the process. 

It's hard to believe, but I think the root of my problem is a bad Negative ground connection on my battery ( HOPEFUL ) 

Thanks again Carl , I'll give an update
