Hi all,
i got my motor in my 36 yesterday, it went right in, in about 10 minutes.
i got the starter hooked up because i wonted to spin over the motor to build up oil pressure. when i hit the starter button it did not crank, co i disconnected the starter cable and checked for a short in the starter circuit and it was clear, the short is in the starter it's self. do you guys know what to look for? i forgot to say that the starter used to work fine , it worked about 3 weeks ago, thanks for your help...Brendan

Be sure the bendix is not locked up. If so, it will act as a dead short.

Also check the insulating washers for the battery connection stud. Sometimes, if the battery connection has been disturbed, the old insulating washers will fail. Be sure to check the one inside the starter under the head of the stud.

I use nylon washers from my local hardware store to replace these when necessary.

Let us know what you find out.

Just some ideas,

Chris.
 
First make sure the grounding strap from the battery to the fire wall is nclean and tight and then make sure the grounding strap to the engine is clean and tight. Then attach a heavy cable from the negative battery post and touch it to the starter post. If nothing, the starter is dead. If you get a heavy click, the bendix may be jammed. John

Brendan as chris and john said, check your grounds, you have a freshly painted engine. Also if you painted the area where the starter bolts to the pan, clean that area to bare metal......Ed
 
when i panted the motor i taped off the mounting surface ,and cleaned the mounting surface on the starter.i removed the starter, and took off the brush cover, i thought that was shorting it out , and i checked it with a ohmmeter, it had no resistance, read 00.0
 
A short in the starter should have created some very hot main cables. Should have seen sparks when bench testing it. Brushes are hooked up the both the field windings and ground. Without removing the armeture or insulating the brushes from the armeture you won't get any resistance. I've seen starters cleaned up with solvents and ended up saturating the field windind insulation and creating a short that way also. Starter assembly bolts touching the field leads will also stop it from working. How are the starter button contacts?
 
Hi, i fixed my starter motor. the stud that the battery cable bolts to , the mica on the bottom side was gone. i took a donor stater motor and used the case. it works good, cranked it over with no spark plugs and i got 35 lb oil pressure hope to have it on the road soon. thanks for your help ,Brendan
