Overhead load center questions - amweath - 08-26-2007 07:21
I'm trying to get my rear camera working. It worked when I picked up
my coach in April. In the overhead load center (above the driver)
is a row of circuit breakers whose power is provided by an adjacent
solenoid. This solenoid is energised by turning on the ignition key.
These breaker are for the dash A/C controls, rear camera trigger, and
various indicator lights. The solenoid is energised by the key.
However, turning the key off does not release it. It doesn't realeas
untill the master power switch is turned off. Are these supposed to
be self latching solenoids? I wouldn't think so. Otherwise, too many
things stay enabled even though the key is off.
By the way, I did find the camera problem. A broken wire in the rear
overhead. Have yet to solder it - on my way to do it now.

many solenoid need major amps/volts to open but less to stay open.
maybe your ign switch is going bad and the only time it pass no power
is when the input power to the ign switch is shut down with the
master power. all other times it is bleeding enough to maintain the
solenoid open but not enough to open a closed solenoid????????????
OR,,, bad solenoid. I would check the solenoid signal post (where
wire from ign switch attach to sol.) with a good multimeter with
the ign switch off. then, remove the ign wire at the solenoid and see
if there is power ;at the solenoid signal post or the ;end of the
removed wire from the ign switch. if power at the signal post it may
be the solenoid is internally screwed??????????
'Self latching solenoid'?? is there such a thing???

Art,
From the sound of it, someone has wired something that is feeding
back power from the solenoid output to the solenoid coil. Once
energized it will not release. I hate to say it, but 'happy hunting".
You will need to determine what new device or new connection is
connected to the line from the ignition switch to the relay coil.

Thank you all for your responses. What I heard was the solenoid is
not supposed to stay up. Now I know what to look for.
I've never heard of a self-latching solenoid either - self latching
relays, yes.
