gkmears Report post Posted May 19, 2021 Needs some advice on two problems. I have a Winnebago 2007 Vectra with Dimensions inverter Model WIN-12X20B3R1T. 2 months ago, I got a message stating battery temp sensor bad. Ordered new one and replaced everything worked fine till last week. Now I am getting charger-off battery high temp. Batteries were replaced in November 2020 they do not feel hot. I hooked up a trickle charger to house batteries to keep them charged everything works fine with trickle charger hooked up. Second problem that is happening is when I hook up to 50-amp service sometimes It shows 50-amp on control panel then next time shows 30-amps this has happened at 2 different locations. I checked surge protector and have good voltage in and out of surge protector. I am thinking my inverter is bad. Not sure why sometime I am only showing 50-amp next time 30-amp. Appreciate any advice you may be able to offer. Thanks Gary 602-369-2157 gary@mearsac.com Share this post Link to post Share on other sites
manholt Report post Posted May 19, 2021 For over heating, is your batteries acid or AGM? If you can remove the caps on battery then its acid and your low on liquid, if its sealed then you probably have a bad cell in one or more batteries....same can also apply to acid....you can have brand new batteries, with bad cell. On your Powerline board it shows your set for 30 amp, press the select amp to 50. Share this post Link to post Share on other sites
gkmears Report post Posted May 19, 2021 Good Morning Carl Batteries are acid. I had the batteries checked last week to made sure I didn't have a bad one. Powerline board it shows set for 30 amp, when I press select button only selects 30 amp or 20 amp. I have had this coach for 14 years and it has always defaulted to 50 amp then I would select 30 amp if park didn't have 50 amp service. Service shops are so backed up here in Phoenix can't get an appointment to just get it looked at for 30 days then could be another 30 days to get parts in. Going to order a battery temp sensor and see if I may have gotten a bad one. Thanks Gary Share this post Link to post Share on other sites
kaypsmith Report post Posted May 19, 2021 You probably have a different issue than temp sensor causing the 30 vs 50 amp problem. Could be a leg on the Shore power wire, or ATS may only be latching on one side causing the 30 amp signal. If you don't know how to troubleshoot for these conditions please ask here on the forum, many with knowledge will respond. I see only two post by you here and no welcome, Sooooooooooooooooooooooo, WELCOME aboard. Share this post Link to post Share on other sites
gkmears Report post Posted May 19, 2021 Yes, I believe there are two problems I am hoping the new battery temp sensor is bad and that fix my charging problem. Then to find 30 vs 50 amp problem I will try trouble shooting the ATS. Thanks for your input appreciate it. Gary Share this post Link to post Share on other sites
wildebill308 Report post Posted May 19, 2021 Welcome to the forum. Double check that the battery temp sensor is installed and connected correctly. Bill Share this post Link to post Share on other sites
gkmears Report post Posted May 19, 2021 Bill - It is mounted on negative battery post and plug into inverter. All fitting are tight & clean. Thanks Gary Share this post Link to post Share on other sites
