still fighting slow crank

[p24-1953]

Im still chasing the slow start. The weak spark was solved by replacing the plug wires and condensor. But the car s still getting slower with each start. It has the proper 00 battery cables and the battery was tested at 6.4v and 600 crank amps. I thought a video might help . It will start every time but man you have to wonder some times... as a note I never let off the key during this video..n

Can't watch video, states it is private. Change youtube settings.

Done thanks for the heads up

Where is your timing set?  Put it on TDC and see if it turns over faster.

2/0 cables are heavy enough. The can, however, get corrosion on the cable ends and there are 2 ends to each cable. if you have any of that green corrosion showing up anywhere in the cable, it's time for new. The ground end of the ground cable is often neglected and if you have replaced the ends themselves with off the shelf, bolt on ends, it's a temporary fix at best. Worn bushings or brushes in the starter can also slow it down.

Perhaps a new solenoid would cure the problem. If the contacts within the solenoid are deteriorated, there could be enough resistance to limit the current flow to the starter.

If the bushings in the starter are worn out, you will never win. My son's truck was the same way, I pulled the starter took it in and the bushising were shot, new bushings and all changed. To get mine running, I got a friend to help. I suggested he do it his way, forget about me and what I've done. In about 15 minutes he found the problem, we fixed it he timed it and it no starts on the 2nd hit. Wish you the best.

Sounds like resistance inline somewhere

[Plymouthy Adams]

what is your amp draw when starting...and what if any voltage drop do you have..start with the known values first..specification are in the service manual..

[dlrides]

1) Check cables/grounding, about 6 times

2) Check timing

3) Rebuild starter

4) Repeat #1

rebuild the starter . replace the cables. they can have corrosion inside that you may not see. captden

Rebuilt starters sometimes are not rebuilt 100%. Under load is when you will know if a starter is good assuming all cables and connections have been voltage drop tested and known to be good.

Starter solenoid bypass:

Well checked the timing and I am set at 1 atdc so timing I think that is okay, rechecked all cables and connections and they looked okay. So I decided to bypass the solenoid and see how she sounds. I think oldguy48 might be right....
