Blower issues

[jambon1]

I have been having an issue with my blower not working. I have a 2003 Crownline 180BR with 20hrs on it. It has been stored for almost 4 years and is in almost good as new condition. Ever since I purchased this boat new in 2003 I have had an electronics issue. The blower was continually blowing fuses, but now when I flip the blower switch, the light on the switch comes on, the fuse remains intact, but the blower does not turn on.

When I put a 5amp fuse in it, it BLOWS. But a 10amp fuse remains intact. But still does not turn on.
Any Suggestions??? Thanks

Re: Blower issues

I don't know what unit you have but my blower takes 10Amp fuse, and the unit itself I think takes 6amps...

I would say it is likely bad blower, pull it out and try it on a battery.

Attwood Turbo 3000. What is the procedure for checking it on the battery??

Eric,

Here is a link to the spec sheet on your blower:

It looks like it only pulls 3.1 amps at 13.6 VDC. If it blows a 5 amp fuse but does nothing on a 10 amp fuse that would point to a bad blower.

1. Do a visual inspection of the blower. Does it look ok or is it charred and have a funny smell or something unusual. If so it needs replaced.

2. Use a meter set to DC voltage and verify that you are getting 12 vdc or more at the blower when the switch is turned on. If voltage is good go to step 3.

3. Remove the blower from the boat. Disconnect hoses and clamps, wires, etc. Take a screwdriver and see if you can spin the impeller inside of the blower housing. If you can't, blower is bad and needs replaced.

4. If all previous steps checked out ok grab the meter again. This time set the meter to the ohms setting. Touch the leads of the meter together. It should read 0.0 or OL. Now take one lead from the meter and connect it to one of the blower motor wires and do the same with the other. You should have a reading close to 4.4 ohms. If it is not close to this, you need a new blower.

5. If steps 1 - 4 are ok. Take a fully charged battery and one a wire from the ground of the battery to the black lead of the blower. Run another wire from the positive terminal on the battery and run it to a fuse (No more than 5 amps) and then to the motor. The blower should run.

I suspect that you will find a problem before you get to step 5. Luckily blowers are not expensive!

Good luck, hope this helps.

Thanks Crabber. I'll try it this evening.

Re: Blower issues

A blower that has been sitting for some time and not used can often be hard to turn and will not spin up. Many blowers you just need to get to the bearings and Lube with 30 weight non detergent oil.

Very good post by Blue Crabber.

Re: Blower issues

The Motor was frozen. I pulled it out and the impeller would not turn. Replaced it Saturday morning with a new one and now I'm back in business. Thanks for all the assistance.
