manholt Report post Posted April 7, 2017 What are the symptoms of a going bad TS? Also, does it have a relay? I'm on shore power now and found out yesterday, that both inverters were off. Started Generator and unplugged from post. Both inverters still off, then got a momentary green light, then off. Turned generator off and hooked back up to post and both inverters came on and is still on! Carl Share this post Link to post Share on other sites
abyrd Report post Posted April 7, 2017 Yep, the problems that you encountered are good signs you need to perform some maintenance before it develops into a more serious problem that could lead to a catastrophic failure. I would start by checking for loose connections on the ATS and to inspect the ATS contacts. The opening and closing of ATS contacts cause an arc and over times the contacts become pitted, that causes a high resistance contact and eventually they will over heat. Make sure you never shut the generator down when it has load on it, especially if you are plugged into shore power. I have spent my career in hydroelectric powerhouses and have seen may failures due to high resistance contacts. Jim Share this post Link to post Share on other sites
jleamont Report post Posted April 7, 2017 Carl, check it or have it checked. Yes there are relays inside, they actually open and close the contacts. unplug the coach and keep the generator off when you pull the cover, just in case! There were problematic transfer switches around your year coach also. IOTA transfer switch is the one that comes to mind but I could be wrong. The one below I believe is the problematic unit, ironically I have that same model, just several years older . I keep a close eye on it with monthly inspections, planning on replacing it in the future as a precautionary measure. Share this post Link to post Share on other sites
kaypsmith Report post Posted April 7, 2017 Carl, did you check the shore power breaker at the pedestal? I assume that the inverters are automatic in case the power fails is why they are both on. If this is true, recycle the shore power breaker. Also does the AC's work now? Few coaches are designed for the AC's work on an inverter. Share this post Link to post Share on other sites
manholt Report post Posted April 7, 2017 Everything in coach worked and is still working fine. I just was not getting any charge on house batteries and heard a clunking sound from where my TS is at. Sometimes it happens then I can go 3 months with no problems! I'll have TCC take a look when I'm there next week. Yesterday, I had to start engine to get enough juice, to bring a slide in...after I got the inverters to work, slide went back out by just turning the key, no engine needed.

wolfe10 Report post Posted April 7, 2017 Carl, The ATS doesn't sound like it is the culprit, since all other 120 VAC things in the coach work. Said another way, the same two hots, one neutral and ground supply not only the inverter/charger, but all other 120 VAC things. And, since you do not say that outlets and appliances that can be powered by the inverter are not working, that suggests that 120 VAC is also reaching the inverter/charger (and then the pass through feature is powering those items). So, it may be that just the charger section of the inverter/charger is not functioning. If this is not exactly what is happening, please post specifically what is working/not working.

kaypsmith Report post Posted April 7, 2017 Relays in transfer switch are 120 volt, no 12 volt supplied to it. I would certainly have it checked out and as mentioned above make sure that they check all wire terminals and contacts for burn signs and retighten all terminals while in the switch. If the contacts are burned, I would have the switch replaced. Depending on use of course, I usually get about 10 years use out of the Iota brand ATS, and I average two times a week to use it. And I agree with Brett, the ATS doesn't sound like the culprit, based on your reply. Share this post Link to post Share on other sites
jleamont Report post Posted April 7, 2017 Carl, what else is in the area of the transfer switch? Perhaps a constant duty 12v solenoid... I found my salesman switch was incorrectly wired and experienced a similar problem last year. Someone replaced the solenoid, they had the inverter tied into the solenoid on the switched side, so when the switch in the front door was turned off it would break the charging line to the house batteries. Its going to take someone sitting at your coach to figure this one out. Share this post Link to post Share on other sites
manholt Report post Posted April 7, 2017 Quote Brett. Probably as you suggested. The only thing that does not work at the moment is the charger. I played with it this morning and now thinking that I have a loss connection or bad ground...Linda, before I could stop her, thumped both inverter/chargers with a rubber mallet. Inside coach it was charging at bulk 14.5 and 14.6, amp was 89 and 62, then started to drop off until both was showing float at 13. 3 and 13.1...it's still there! Women!!!

wolfe10 Report post Posted April 7, 2017 Percussive repair! I would sure check the connections in and out of the inverter/charger. Share this post Link to post Share on other sites
