Useful technique to assist compression tests

[Tony Lum]

Hi gang,

Needed to check the compression in my 87.5 CGT over the weekend.  By 
studying the wiring diagram, I found that if you pull the horn relay 
(position 7) and the brass shorting strip in the automatic interlock relay 
(position 8) and  jumper # 7's "34" contact to # 8's "36" contact together, 
you can turn over the engine.  I used a remote starter (Harbor Freight 
Tools Item # 35448) and cut off its alligator clips and crimped on 1/4 inch 
male disconnect contacts.  That made it easy to insert right into the relay 
contacts.

So it was a simple task to watch the compression gauge while pushing the 
starter button.  I also removed and grounded the ignition coil's output and 
tied the throttle wide open to do the checks.

Regards,
