Tech Talk / Re: Powering Atwood Furnace with 12V power converter - Issues!
« Last post by Great Horned Owl on November 21, 2017, 09:46:27 PM »
Joel, I think a 40A power supply (2x the size) is about $25 more. The issue with a battery is that there is no DC system on this unit, it's all AC. In order to use the nice little Atwood furnace we needed to install a converter. So if we put a battery in, it would discharge (the furnace pulls 11A) and not charge (Need more than 12V to charge a battery)

The converter that you installed is intended to charge batteries  I will keep ayours charged with no problem.

Have the same issue. Appears to be a circuit short on the control board.

I have gotten it working by removing the Ground wire from the 4-place ground bus on the side of the housing (just above the circucit borad) the blower is still grounded via the case so it runs.  But I've not yet had time to dig farther.. .Too many othe repairs at this time. Perhaps next week.

Just got a bypass for the Lube Pump controller installed.  Had to replace the pump last summer, New pump occasionally "Blips" a short.. This blows the fuse.. Tried a circuit breaker figured the short delay might save the day. Blew the controller.. Fixed that (Simply trace fail, soldered a jumper over the trace.. Yes I know how to do that) so the controller now works but I'm concerned about drawing that kind of current via the controller.. So I installed a relay

Controller powers Relay. Relay powers pump and sensor switch.  Should work.

I may, however, have disabled one of the sensor functions.. IF SO a light bulb will fix it.. Just have to splice one in.

Hey John, thanks for the info. What sort of vehicle is your furnace in? Standard RV? You got me thinking on the path that maybe there's a grounding issue, because there's no ground to frame, the ground wire just runs to the converter common terminal. I could try your trick but the unit is brand new so I'd nervous to void the warranty

If the problem is insufficient starting current, adding a small battery (such as a motorcycle battery) will be a lot less expensive than buying a bigger power supply.

Yes the error code is for airflow/limit switch but I went through that all with Atwood over the phone. Sail and limit switches are both good. The vents are wide open and there's way more return air space than the specs ask for.

The thing I'm wondering about, regarding the starting current, is that there's a 15A DC fuse (from a car) in line between the power supply and furnace as well as the furnace's breaker switch, also 15A. So if it's pulling from a 20A converter, how can it be pulling more than it can supply, without blowing either of the 2 fuses?

Last week...My wife asked Kaiser Medical if she should maybe try CBD oil for her severe arthritis...They informed her if she tested positive for Cannabis they would revoke her prescriptions for pain and anxiety meds and it may likely jeopardize her scheduled knee replacement surgery next year.

   she is currently prescribed  2 - 10mg oxys,   5 times a day for pain.. by a real Doctor.  ( a medical conspiracy ?    hmm...) 

  I like to drive her everywhere she wants to go ..but technically it's legal for her to drive and she feels fine to do so.

PCs, Communications, Electronics / Replacing a Lenovo laptop keyboard
« Last post by Tom on November 21, 2017, 09:15:14 PM »
Call me a klutz, but I occasionally spill a liquid on my keyboard. Last time around it was a full glass of wine that I misplaced on the edge of a 'high' ceramic coaster. Chris immediately got her hair dryer out, but that was probably not the best move. After a few weeks of repeatedly escaping out of a stuck key, I ordered a replacement keyboard for my Lenovo laptop.

Cheap on amazon, and delivered from China under Prime.

This was the easiest keyboard replacement you could imagine. Only two screws on the back of the Lenovo let the keyboard loose and the replacement installed. No more stuck keys  ;D

Another thought on the topic.  Has anyone ever heard anyone say, "I would use marijuana if it were legal, but since it isnt, I wont".  My view is that virtually everyone who wants to use marijuana is.

Your story reminds me of the time we were docked with our cruising club at a yacht club. Since there were going to be fireworks, I kept telling Chris to keep the door (glass or screen) to the salon closed, to ensure we didn't get uninvited guests aboard. In the middle of the night I awoke and felt something crawling up the leg of my PJs.

I wriggled and jumped around, and eventually this little field mouse came out from under the covers, and crawled across Chris' face. Just then, she woke up and was not a happy camper. The following day I set a trap and, in the middle of the night, heard the telltale sign that we'd caught it. I periodically have to remind Chris about uninvited guests aboard and in our S&B home  ;D

Where did you find a F350 SRW with a GVWR of 15,000#?  I have a 2017 Ram Dually and the GVWR on it is only 14,000# I don't know of any newer 350/3500 duallys with over a 14,000# GVWR little alone a SWR.

They must have started building new SWR 350/3500 trucks with 22.5" semi tires on it to get to that GVWR.  ;D
Whoops   :)
 should have typed a 11500 lb gvwr in my above post.
