Hi my name is Robert...
Are you talking about the water pump? When the water pump is running and you try to use the step is that when it is blowing?
This sounds like a battery issue and before we try a phone chat I would have those checked and rule that out as a proximate cause. If yours are over 3 years old there is a good chance they are "toast" as the saying goes. Most places that sell batteries can test them for you or you may want to have a good mobile tech come over to your location and assist you with this. If you do take them out to be tested, be sure you mark all the cables and take a few photos so you get them hooked back up correctly. Easy to get that wrong if you don't. I think this will resolve this for you. IF not, we can further into the diagnosis. Just get back to me as all follow ups are included in our fee.
Perhaps. There may be a shortstop breaker that has tripped. They are usually near the batteries or under the hood in the Battery Control Center. Push the black button in to reset it. If he knows electricity, he should be able to track this down. But, FYI............even brand new batteries have a pretty high failure rate. I am attaching a link to a photo of what he is looking for. http://www.surplus-electronics-sales.com/images/medium/122-1012%20Short%20Stop%2028V%2030A%20CB%20sm_MED.jpg
It may be in the step well if that is where the house batteries are .
You are most welcome! Get back to me if we need to dig deeper into this and please take some time to enter a rating on my assistance to you relating to this question as that is the only way I get credit for helping. Thanks!
Some are auto reset breakers. You can check for power going through it with your meter. OR jump over it to test that this is the problem. IF power is restored then you know it is bad. They have an amp rating on them so check that if you need to replace it.
Just checking back in to see if you were able to get this resolved or do you still need additional input from me here?
Did he look in the fuse panel under the hood? Sometimes, the step fuse will be in there. Worst case......have him wire in a new hot lead with an inline fuse from the battery. That would at least make this operable.
I noticed that you haven't gotten back to me relating to your question and I am wondering if you saw my earlier response to you a few days ago? Were you able to get this issue resolved or do you still need some input from me here?
So if the step works when you are hooked up to mains, then the problem is that the battery is either bad (even new ones can fail and do) OR it isn't being charged and is too low on voltage to operate the step when you aren't on mains. Did he check the charging voltage AT the battery when you are hooked up? It should be about 13.6 VDC or close to that.
Just checking back in to see if you may have missed my response to your question a few days ago? If you still need some assistance and input from me here, please get back to me. Thanks!
O.K..........not a problem. I will be around all weekend.
