[HAM] Starter motor of my C3 is getting kind of "tired"

[Dave Bishop]

The organ has one start switch and one run switch.  The starting procedure 
is to lift and hold the start switch only for 8 seconds, add the run switch 
for four more seconds, and then release the start switch while keeping the 
run switch on.

Looking from the back, the start motor is on the right and the run motor is 
on the left.  If you have someone else lift the start switch while looking 
at the start motor's connection to the TWG, you should be able to see a 
small bendix gear slide to the left and engage with the gear on the TWG 
shaft.  With the organ off, you can move the gear back and forth with your 
finger.  It should slide easily, engage fully on to the TWG gear, and 
disengage fully on its own when you let go.  If it doesn't, post back and we 
can tell you how to clean it.

Its possible that the organ needs oiling:  two teaspoons of Hammond oil in 
each of the two funnels located in the top center of the TWG dividing the 
TWG into thirds, plus eight drops in the rectangular funnel at the top 
center of the run motor.  It may take a week to see the results.  Spinning 
the TWG by hand should result in it turning freely at least six or eight 
revolutions.

You could have a defect in the switches, switch wiring or the load resistor, 
or less likely, a dead winding in the motor.

Regards,

Dave Bishop
