A Problem Solved?

I spent most of the morning working on client stuff. It seems like they all want things done at the same time, and this week has been a perfect example. Every thing comes to a head at the same time.

I mentioned back in January after I installed my new power converter/charger that there was a slight problem with the voltage output.

Powermax 110 Volt to 12 Volt 55 Amp Power Supply Converter Charger

The Powermax unit has 3 voltage levels: A Bulk Charge Mode at 14.4 volts, a Absorption Mode at 13.6, and a Float Charge Mode at 13.2 volts. When you first power up the unit, it starts out in Bulk Charge Mode for up to 4 hours, before dropping back to Absorption Mode, which is where it will stay under heavy 12volt usage. But with mostly LED lights, our unit usually runs in Float Mode.

But Float Mode is 0.1 volt too low for the rig power system to switch over and keep the rig engine batteries charged. Up to now I had a separate battery charger on the engine batteries that I plug in every we part. But this is a PITA, and just one more thing to do when we park.

So this afternoon, I set up something different. Using an AC Timer like this one,

Brinks Timer

I set it up to turn the converter off for 30 minutes every 8 hours around the clock. When it turns back on, the converter starts back up in Bulk Charge Mode and then drops to Absorption Mode. Both of these voltages are high enough to keep the engine batteries charged. And so far today it’s working fine. I’ll let you know how it goes.

I had planned on trying to paint the center section of the rig bumper this afternoon, but by the time I got out there, the sun was directly on the bumper, making it too hot to paint without it drying too fast. So maybe tomorrow.

For supper tonight Jan heated up our leftover Grimaldi’s Pizzeria pizza from the other night, as well as the Fried Green Beans from last night’s Joe’s Farm Grill visit.  Both just about as good as before. We both agree Joe’s is a place we would like to go back to before we leave.


Thought for the Day:

The more I get to know some people the more I love my cat.
