INVERTER NOT FUNCTIONING

Should be inside the inverter.
Which inverter do you have?

its part of the inverter. called a transfer switch

FWIW....my RV mechanic says that CONVERTERS can get weak over time then fail...but INVERTERS either work or they don't.

1999? Might be time for a new one. G'luck!

I am looking for the switch that determines if the 120 volt power is being supplied by power hookup, generator or batteries.

That would be two different items.
A standard transfer switch is used to switch between shore power and genset. It is normally located in a void around the converter if equipped.
The inverter has or most have, an internal switch that goes from shore-power/genset to batteries. It is located inside the inverter. The inverter makes 120 volts AC from 12 volt DC in an RV.
Some higher end rigs use an inverter charger. you need to identify if you have a converter or an inverter/charger. Makes and models would help.

Exactly.

what is the exact problem
no power when on shore power

no power when running the generator

no power to TV and special outlets when on battery ?

when the main TS fails, normally you get shore power and no generator
or maybe no power at all

if the internal TS relay inside an inverter with power pass thru fails
then only those outlets are affected
usually dead , no matter shore or generator

50amp 4 prong service or 30 amp 3 prong service

normally with a 50 amp service, the TS will be in a separate box, with 3 cables, shore, generator, and house some where in between the generator and the shore cord, with my Safari thats an outside bay where the inverter and charger are located

a 30 amp service might have a smaller relay tucked in behind the breaker panel or it could be in a box under a cabinet

For the record - inverters take DC current and change it to AC. In the case of most RV's, 12VDC to 120VAC. Most unites have Converters in them by default, which take the 120VAC and convert it to DC to charge house batts. Not too sure which OP is talking about.
