Fatboy issues, any ideas? Pump will not start.

Phil, This happened to me last week. Turns out it was the relay. I went to an auto parts store and replaced the relay with a starter relay and its works great. This is the relay I used from Auto Zone - Duralast Gold F492G starter solenoid.

What? No pictures????

I'll post pics tomorrow of how it's wired.

Phil, if you open up the case of the old relay you will probably see where it burned up, at least that was the case with mine. I'm going to switch out the relay on my backup pump also to avoid future problems.

Make sure that the the wires are on the right terminals on the battery. I ran my pump for a month and had the pos and neg backwards. It started too act up. I switched the wires around then it ran fine

Phil, Please call me, I can help. Fat boys are much less complicated than you think. It is most likely an electrical issue. Brian

I agree most likely cause is the relay relays go bad all the time I keep a couple of spares in the trailer have not had to replace yet but I made a lot of money replacing relays when I was an auto mechanic (when something electrical goes wrong with your car check them first)

Sorry, I shouldn't have posted this in 2 places, I'll update both posts and they can be merged and moved one place if deemed necessary.

Barry, I went to Advanced to see if they had the starter solenoid, but they said they couldn't pull it up based on Autozone's part #. I already ordered one, so I will probably wait for now, but Marcus did say there was an even less expensive option in an electrical store in the other post.

If this burned up, does that mean my pump was cycling too much? I've been using it since August 2010, but it definitely got a 2-3 month break in between with winter. Since the season started, it's only been used about 8 times.

Here is the problem, you guys were right:

should be a small wiring diagram on the relay any relay should work with the same diagram on it take the relay with you to any auto parts store and tell them to get you the best one that matches and get a few spares could be too much cycling if you are using a small hose this will happen but sometimes relays just go bad

anything electrical will go bad

I have the setup from Bob at Pressure Tek, he pre-wired it and all of the hose came with it (1/2").

Guest

yep thats what i have and i think i cycles a little too much but have not had the relay go bad yet keep some extra relays you should be ok they do go bad even if everything else is perfect

Roof Cleaning Severna Park MD · guest

Thanks! I may try to adjust the pressure a bit to see if it can be zoned in a bit more. It seems to be fine, but Bob said it shouldn't have fried that soon if I didn't have a cycling issue.

Here are the pics of my starter solenoid I have replaced my stock relay with. When I asked for the solenoid at the parts store I told them I need a starter solenoid for a 95 Ford V-6 ( they seem to only know how to search parts by vehichle, so I made one up)

Roof Cleaning Raleigh NC · May 12, 2011

Hey Barry, have you adjusted the pressure in the accumulator or did you keep it at the factory pressure. Which I think is 20 psi. I haven't even checked mine. Just wondering if anyone is pumping up the pressure or lowering it or what.

David, I have mine set at 50psi as per Bob at PT.

Roof Cleaning Severna Park MD · guest

Barry, thanks for the pics. I purchased that start solenoid today, but I am using it as a backup since the relay is already on its way from Pressure Tek. Do you find this to be a better solution or just the same?

SEE OUR WORK HERE!!! · Guest

Phil, I just hooked it up maybe 6 jobs ago. I believe its way better (the pump seems to be a bit more powerful). I was told that the FatBoy stock relay is a 30 amp relay and when it first starts up the FatBoy draws 65 amps these starter solenoids I believe are rated for 80 -100 amps so this should take care of the fried relay problems the Fat Boy is known for. Keep in mind I don't know much about electrical systems or starter solenoids or for that matter pumps, this is all from the various resources of research I have done regarding this issue and decided this is the route I'm going. It does seem to be working alot better set up like this though.

Thanks for the info, I'll definitely give it a shot when the next relay fries!
