1963 4010 CRANKS SLOW

Also, it is winter time and batteries are lowest and oil viscosity is highest.

Have Auto Zone check the batteries cca. Need 200A or so to get that baby to rolling over.

Remove all your connections (in addition to those recommended herein) and shine em up nice and brite, including the lead to lead connections at the battery and put them back together nice and tight.

I had a 4010D that I bought very used, and the owner had one trolling motor deep cycle battery that he used for power, of all things. Judging from the looks of it he had succesfully used it for a long time. TM batteries aren't supposed to put out that kind of current, but this one apparently did.

I redid the starting loop after purchasing. I built a battery box adjacent to the starter and put 2ea 950 cca size 31 truck batteries (wired in parallel for 12v) in it with 00 wires directly to the starter. Cleaned up the wiring and starter case (grounds) as mentioned. I guarantee you , any day of the year I could hit that baby and within 15-20 seconds that baby was roaring to life.

I'd clean everything up and have the battery checked before redoing the starter. But I have had one go out with worn out brushes and that's what happens when the brushes get short.

Good luck,

Mark

Another contact point often overlooked is everyone cleans the battery connections, but where it grounds needs cleaning, and where it connects to the starter as well.
