2005 Holiday Rambler Neptune
Cummins 300 hp/Allison
35000 miles
Problem: ABS light lit, engine seemed low on power.
On way west from Brandon, MB. Towing car, first time with this MH.
Condition worsened and eventually we had to stop. I checked that everything seemed to be normal in battery compartment. All "OK" but did NOT use a multi-meter..
Last year we had similar trouble and eventually the alternator was reconditioned in BC.
By using the generator and jumper cables connecting engine and house batteries we limped to Swift Current, SK. I wasn't too happy about using the cables. Tried about 6-7 places in S.Current but no place could, or perhaps, wanted to find the problem. Most were too busy.
Limped further west to Medicine Hat, Alta. with my wife driving the car.
Same problem, most places too busy. An rv tech who was passing volunteered to find the problem. I told him I suspected the alternator. He found the alternator was not functioning well.
Next day we found a shop, told them to install a new alternator. two hours later we were on our way. Problem solved. Engine had lots of power. Moral...check electrical system before leaving and, for me anyway, never install reconditioned items.
