Re: [DML] Constant tripping of the cooling fan breaker

Ken.
I can almost answer the question in one word. HEAT. From the current draw of 
the fans. How many miles on the fans may have the brushes worn down and they 
will draw more current which produces heat. I wouldn't keep adding higher 
current breakers, you may be masking a problem and burn up some wires. This 
is why I don't use circuit breakers in the fan circuit of The Fan Fix, I fuse 
at 15 amps and in most cases will handle the load.
If you have any current measuring equipment, the fans ( both ) coming on will 
surge at around 60 amps and run ( both ) at 28 to 30. 1/2 for ea fan. You may 
have one or both fans running sluggish and drawing more current.

<< I've come across a problem I've not been able to solve. The circuit breaker
to the cooling fans keeps tripping when the air conditioner or the otterstat
has them switched on. It happens after the car and fans have been running
for a while and the breaker has become hot. I thought I may have just had an
old or defective breaker (40 amp) but the replacement does the same thing. I
have a FanZillia, the fuses on it are holding and both fans turn easily. Why
are they drawing so much current? I'd just jump the breaker and rely on the
fuses but That's just not a good answer.
