close to overheating
Took her out for a long cruise today, to do a little fresh motor break in. I ended up getting stuck in traffic. Keeping an eye on my gauges, I noticed my temp creeping over 210. It's never done that before so I kicked open the vent to blow some heat, to keep her calm. I got home safe... applied power directly to the fan... Works! Pullingd the relay and applied power to it... It .Kicks on/off. What else could it be? I did probe around in the PCM a little. According to lunghd, pin 5 to ground should have continuity... I did not! Where did it go?
On the bright Sid I fixed d my low beam issue while I was in there. |
Every Fresh Engine...

On the bright Sid I fixed d my low beam issue while I was in there. Every fresh engine I have ever installed ran warmer until everything seated and friction was reduced to normal. New Marine Engines are the worst because of such tight tolerances. |
So the "fresh motor" is the reason my aux fan never kicked on?
|
No, I'm guilty...

No, I'm guilty of not reading it correctly. Somehow I took it that your fan Was also working properly. My fault. |
It s all good. Just trying to massage out all the bugs, since it's back on the road. I have more problems now, after the motor build, than I did beforehand. I'm down to the little amount of coolant I lose (don't know where) and the aux fan not kicking on. I also need to recharge the ac still, so that works again.

Long day for me too by the way ��. I guess I never specified that it didn't kick on.... So... My bad!

Continuity?

Curious? I am guessing you already swapped the relay with a working one to check it but might want to check the continuity of the wire running through the loom to the fan. I know I have pulled or pinched many a wire in hard to see places doing engine R&R work :) I'm trying to find a circuit diagram for you now. |
I didnt try another relay per-se. I pulled out the relay and tested it with a power supply and multimeter and it functioned like it is supposed to. A pinched wire could very well be the cause. I have a Haynes manual to my left and a 95 FSM sitting in my lap. :)

Good deal

Curious as to what you find, please let us know :) |
Roger that!
|
You got Ac ? Does it come on with Ac running ?
|
I cannot operate my ac yet, it needs to be recharged.
|
Jump it?

jump the A/C low pressure switch for a couple seconds to see if the fan does come on?

Are we right? lol

x2 got a paper clip ?
That circuit has to be closed to ground in order to make it think the A/C is on right? or is there a second circuit from the switch? lol |
