Intellitec BCC Isolation Relay
I have a possible issue and was looking for some help. Here is the scenario. This is an Intellitec BCC Mini-Gas #53-00524-100. I also have solar panels and a digital controller that tells me the status of the panels and battery voltage. I will try to put as much info as possible in this first post.
NOTE: Solar Panels are connected to Auxiliary Batteries.
ISSUE: Normally when RV is started, the solar charge controller goes to 13.6+ Volts and Green Charge Light goes all the way to the end. Red Charge Light Is On.
Yesterday when I went in and started the RV it did not do that so I checked a few things. Here are the 3 things I checked so far.
Not Plugged In – Not Running – No Sun on Solar Panel.
Reading on Solar Charge Controller – 12.5 Volts – 0.0 Amps – Green Charge Light "2/3 across" – Red Charge Light On.
Battery Voltages - Checked At Batteries
Auxiliary – 12.45 Volts
Chassis – 12.65 Volts
Tested Auxiliary Start Button In BCC – Heard Click of Isolation Relay
Plugged In – RV Not Running – No Sun on Solar Panel
14 Seconds - Heard Click of Isolation Relay
Reading on Solar Charge Controller – 13.5 Volts – 0.0 Amps – Green Light "all the way" – Red Light On.
Battery Voltages - Checked At Batteries
Auxiliary – 13.5 Volts
Chassis – 12.65 Volts - Didn't show increase.
Not Plugged In – RV Running – No Sun on Solar Panel
14 Seconds - Heard Click of Isolation Relay
Reading on Solar Charge Controller – 12.7 Volts – 0.0 Amps – Green Light "2/3 across" – Red Light On. - Always went all the way across when RV was running.
Battery Voltages - Checked At Batteries
Auxiliary – 12.60 Volts - Didn't show increase.
Chassis – 14.33 Volts
It appears that that when plugged in only the Auxiliary Batteries are charging and when not plugged in, but RV is running, only the Chassis batteries are charging even though I can hear the click of the Isolation Relay in all tests, which when engaged should charge both.
Any Ideas? Think it needs a new isolation relay? Anyway to test it?
Thanks in advance for any replies.
