I had orignally posted this problem under the Talkback forum, but under advice am reposting here.
I have a 2005 Winnebago Vectra 36RD with an Onan RV Quiet Diesel 7500, Model SQDHDKAJ1145H. On our last trip, after arriving at our destination, I tried to start the genset and it would not crank - silent, would not turn over. Instead I got the error code flashes on both the Dashboard and Genset siwtches. After checking it gave me 4 + 6 flashes (error code 46) which the manual says is low voltage and suggests checking the batteries and cables.
I then checked my batteries which were fully charged, the battery terminals and the battery cables on the back of the genset. I checked voltage at each point and although there was slight corrosion on the cables connecting to the back of the genset, I cleaned them good and reconnected. After insuring that I had good battery power and connectivity, I removed the inspection plate on the Genset for the coolant and fuses, checked the three fuses with a circuit tester. All three tested good, I replaced them and got the same result - error code followed by 4 flashes then 6 flashes?
I have been fortunate that we are connecting to land power each night which charges the batteries. I also tried connecting a 12-volt battery direct to the terminals at the rear of the genset - bypassing the house batteries and cables and had no luck. Any help is appreciated!
