Huh … of all the things we all thought the problem could be, turns out it was something no one put further. Add the fuses in the charger wires to the list of “why won’t the coach start” things to check.

Now … why were the fuses blown? Inquiring minds certainly want to know!

I’m not convinced the problem is solved.

Even if the batteries were not getting properly charged my concern would be to find out why they discharged. Coach lights are 12V so if that is what Charles thinks was the load the equalizer would have had the 12V side drawing power and the 24V side would have been pulled down as the equalizer maintained the correct relationship between the two voltages.

I had a similar problem last year. My coach had started fine the night before, but when I tried it in the morning, nothing but a few clicks. The batteries were at 13 volts, but still wouldn’t start. I had been using the old 24 volt-35 amp charger that was original when the bus was new, the batteries were 2 years old, but were fried from over charging. So your batteries can be reading proper voltage but not have the amperage to anything. Three of the batteries were no good when checked, so I bought all new batteries and it started right up.

I had a similar problem last year. I had nothing when turning the key. I found the front bumper release had been pushed and it released bumper. Closed bumper and all was O.K….Steve

One idea is to simply find your starter and be certain the large bolt holding on the power supply to the starter is tight. Check all bolts on the starter particularly the main one. Do not touch the engine or any other metal with your wrench….. you will know why I said that if you do. Sometimes these bolts will back off and if so, it will appear dead.

Was finally feeling a little better since surgery last friday so decided to check the batteries after replacing the fuse. Started up like a champ.

So the new question is why did the fuse go?

Ran it for a while, aired it up and releveled it

That would be my concern. Usually the fuse blows because there is a strong draw on the circuit, a short, or an overload on the circuit. But in this case, the fuse is between the charger and the batteries … correct? Please confirm. If so, why would the fuse blow? I’m neither an electrical engineer or an electrician.

I’d suggest contacting the manufacturer and see if you can get to an engineer who might provide you with some insight into what could cause it. Please keep us posted.

Dick,

The fuse is between the charger and the battery.
