I have the PD9145A with Charge Wizard in our TC. The last two trips while topping off the battery (battery down to about 60%),with the Honda 2000, I could only detect 13.3 Volts on boost and 12.7 on Normal mode. The strange part is the first time it happened when I got home I checked it and it would put out 14+ volts on boost on shore power and when I hooked up my Honda it also put our 14+ volts. It didn't do the same when I checked it this last trip. Any ideas if it is the Wizard or the converter causing the low voltage or is a call to the factory in order? Oh, I did pull the batteries (two T-105's), the first time it happened, and checked them and cleaned all the terminals.

Was the voltage measured immediately when you started charging or after an hour or two? It will take some time to get the voltage up with those batteries and 45 amps charging. Otherwise you probably need a new converter.

Quote:I could only detect 13.3 Volts on boost and 12.7 on Normal mode. Depending on how low your batteries are and the size of the charging cable this could be normal. Just because the charger is capable of 14.4 volts does not mean you will have it at the battery. If the voltage is increasing as the battery is charging it is probably fine.

If the battery is only at 60% it should be getting the whole 14+ volts. Doesn't matter if I check voltage 1 minute or 1 hour after I start charging it goes to 13.3 within a few seconds and stays there. I just now hooked up my FW that has the PD9260 and with 12.5 volts at the battery it is now charging at 14.2 in boost. How can I tell if it is the Wizard or the converter on the 9145? Darn, I had an extra Wizard and sold it!

Trying to get to Sam's point from a different direction, are you measuring the voltage at the battery or at/near the converter output? Measuring at the battery might not be valid for diagnosing if the converter is putting out the correct voltage. You could disconnect the Wizard and see if the converter runs at its default voltage which I think (from memory) is 13.6 .

I don't have a PD but my WFCO will put out full rated power into the low battery and it will take over an hour for the voltage to climb into the 14.4 range from an initial 13.2 volts.
Your 9260 will push the voltage immediatly higher than the 9145 even if both are working properly because it has more amps. And the voltage will climb to 14.4 faster with the 9260 as compared to the 9145.
Ultimately you may need an ammeter to verify you are getting 45+ amps out of the 9145.
Try putting the 9145 in boost and measure the battery in one hour.

What size wires are between the battery and converter, and how long is the run?

I have had the PD9145 for about 3 years. I measure at the battery. It has always pumped out 14+ volts in the boost mode. It has now quit doing that and will only put out 13.3 in boost mode. Like I said the battery was at 60% and SHOULD take the whole 14+ volts. I am sure something is wrong but don't know if it is the Wizard or the converter. It is at the storage lot now as I am getting the FW ready for a trip and just figured I would order a Wizard or a converter if either is bad so I could just do the swap when I brought it home. I could take the Honda down there and unplug the Wizard and see what it dose. Could just order a PD9260 and be done with it, but the "boss" is getting a little tired of me throwing money at these things.

I have a PD9160 with Charge Wizard. When my batteries are down to 60%, my PD will be in boost, and may be trying to put out 14.4 volts, but the battery voltage is still down at 13.3 to 13.4 until the state of charge rises. In the mean time, the PD is putting all 60 amps into the batteries. The voltage won't rise until the charging current drops below the current limit (60 amps in my case, 45 in yours).
I don't think you have a problem.
