The gen start module had been installed, but we wanted to test it and make sure it was working the way we wanted it to... we had gone through all the settings a couple of days ago and had it configured the way we wanted it, but we hadn't made sure it was working according to our understanding. So, this morning, we decided that we'd test the temperature control.
We unplugged from shore power. Carl set up a space heater near the temperature probe so we could test it with the temperature we wanted programmed. We got the temperature up beyond the set point, and the generator came on... but it only ran a short time and then cut off. We tried it several times... we had it programmed that the generator should run for 2 hours if it started due to a temperature control, but the longest we were getting it to run was 5 minutes or less... and the temperature had not come down (since we were still heating the probe).
So, we called Magnum Energy to make sure that we were understanding the functionality correctly. The technician went through all of our settings with us, and then said that we needed to go to the gen start module and do some tests directly on it... well... it is installed within a bay that has a lot of stuff stored in it... so we said we'd call back when we were able to get to it.
We pulled the things out of the bay, Carl got in where he could see the module, and we called Magnum Energy back. A different technician got our call this time (there are 4 currently working), and he talked us through testing the gen start module. Carl did a lot of different tests... and ultimately, the technician indicated that the module was correctly installed. But... we were still having the same problem. It appeared that he was in consultation with another technician, and they came to the conclusion that we have a faulty gen start module... but they have never seen this specific type of error occur before. They suggested that we ask NIRVC to install a new module and see if that corrects the problem. From what he said, it appeared that they don't know whether this is a hardware problem or a software problem... if hardware, a new module should fix it, but if it is software, we'll have the same problem on a new module... and then, I got the idea, it will be more challenging.
So, we talked to the service advisor at NIRVC, and he is scheduling the installation of a new module (we aren't sure that they actually have another module here, so the part may have to be ordered).
All in all, we spent about 3-3.5 hours debugging with Magnum Energy and then time talking with the service advisor -- so that took up a good part of our day. More later on what took up the rest of the day!
Some pictures:
Auto Generator Start module installed on the side of the bay near the roof |
Inverter Charger - also in the bay - installed near the ceiling of the bay |
Documentation picture for future reference... |
BMK Shunt - also installed while the RV has been here at NIRVC |
At least he could zoom in then and see that they were all "down" or to the right or OFF (which was evidently how they should have been set in our system). |
