Re: [DML] Could the wrong battery have possibly damaged

[mike p <cambpd@xxxxxxxxx>]

Thanks for the advice Dave. 
  I didn't think the new battery could have caused the problem but last  night I would have believed anything.  I did everything below with  the ignition key turned on:  I jumpered out the otterstat wires,  no fans.  I turned on the a/c and the compressor works, so the  common diode can't be the problem.  I jumpered out the 35amp  circuit breaker for the fans, nothing.  I checked the voltages on  the fan fail module base with the ignition key on and no voltage!   Tomorrow I'm going to pull the fan relay and test for voltage  there.  Whatever component/thing it was last night, it caused the  fans to fail after being on for oly 2 seconds.  The cooling system  seems to be working fine now except for the fans.  I lost about 2  gallons of antifreeze when I was replacing the rubber hoses and have  put 2 gallons back in.  I'm running out of things to check!   I recently had the a/c system repaired for major leaks and the car had  to run for a long time in hot weather with the fans
 on.  The  alternator belt broke after I left the ac shopo and had to be replaced,  that was lots of fun, which is why I decided to replace all the hoses  because they were so bulged out with the water pump not working.
  
  Thanks again for your advice.
  
  Mike

  will not allow the compressor, and therefore the fans via the diode, 
  to engage. 
  
  In my experience the otterstat itself is very fragile in terms of 
  being overheated. I've watched them die in the process of being 
  overheated. Sometimes they short, usually they open.
