Grounded the Carb cooling fan but no go (1 Viewer)

Man warm starts suck right now.
Grounded the carb cooling fan on 85 fj60 but still wont run after the engine is turned off.
What should I check next?

You tried to hardwire the fan to make sure it runs?

I have not, been meaning to stop by my friends shop who can help test it. Thanks for the reminder.

Just run a jumper from the battery to a prong on the connector. Then a ground and if your fan is good, it should run. The next fault to check would be the sensor on the engine block.

If you hook it up backwards it won’t hurt it necessarily it’ll just suck rather than blow

If you end up needing a new one I have one for sale. Still on my 60 since my conversion to a weber and desmog. Runs fine, just not hooked up since the changeover.

Thanks all! I’ll gice it a shot after we get some energy outa the 4 year old.

Might not be the fan at all. Behind the passénger kick panel is the cooling fan relay. It’s almost exact to the emissions control board. The connections can be reflowed the same way.
I pulled my fan and cleaned everything and noted the little magnetic bushings or whatever (excuse me I’m getting over the flu) had very little wear. Put it back together and still nothing. Hardwired and still nothing. Found a used working relay and now it works.
So that’s something to look at as well.

I’m assuming I can run a multimeter in the relay to check it yeah?

 

[Rube]

Hardwire it first and make sure the fan works, then I’d start looking at the relay.

 

[IslandJ]

Hardwired the fan and it worked. Ill look into the relay now. Is there a way to tell if its functioning or not?

7.5 amp dome light fuse ok?

Done light does work so I was assuming it’s good. I’ll double check when I get home.

Hi, Look for cold solder and lose joints and resolder. Mike

 

[IslandJ]

Looked up “cold solder” and everything looked okay. These 4 points look tarnished. Could that be the issue?

 

[roadstr6]

That could be the issue. Hit them with a soldering iron to re-flow the solder and try it again. FWIW, this little relay can cause a parisitic battery drain if it's faulty. Try it and see what happens.

another vote for sensor on the engine block

If he’s already grounded the sensor wire the sensor should now be unnecessary

 

[IslandJ]

Yeah sensor wire still grounded.

You’ve now surpassed my level of experience and expertise so I’m going to sit back and watch. Hopefully soldering will help you. If not, you could easily wire in timer switch and manually control it each time. I believe a few people have done something like this already.
