[tcb] Re: (HOU) Glen Rose 9/22-24,2006

I'm trying to remember.....
Do you have the same Radio Shack radio installed in your bus as I have in my busses?


If so, that auxiliary radio kill switch is needed for isolating the radio from drawing current when you are parked.

The clock and station memories power feed can remain hot, drawing very minimal power drain, but the illumination, and especially the feed to the radio's class A power amplifier, need to be isolated.

Without the isolation switch, you need to feed the radio through the on-off switch of the bus, and that precludes camp night tunes.

Update:

I cleaned the ground strap from the transmission mount. I installed a new ground on the battery and clean all the connections plus where it attached to the frame.

Re-installed the battery (Showed 13.7 volts on the meter this morning)

Plus Changed an on/off switch I installed back when to turn the radio on and off.

Turned the key and heard the prettiest sound in the world . An engine turning over and it even started.

I'm up and running again. I might go out for a ride tonight now.

Thanks to everyone for their suggestions.

The coil in the relay can fail, of course, and an ohm meter will show this, should it be the case4, but typically, coil failure that will be due to back EMF, induced by the DC voltage collapse across the inductance of the relay's coil. Placing a diode across the coil in reverse polarity will kill any back EMF spikes, minimizing premature failure of the relay's coil. The diode's voltage rating should be well above the normal 12 VDC actuation value.

An equally common failure mode for these relays is due to corrosion on the contacts. The voltage is so low as to not properly cause a spark on the make-break cycle of the contacts. A spark would serve to self clean the contacts (similar to the self cleansing action of polar relays on old teletype units)

And yes, the relays will fail. I have had two failures in the past ten years, I would suppose.
Each failure was of the "intermittent type" created by corroded contacts.
Pull from the socket - replace - crank on.

If the battery doesn't cure your ills , put a meter on
the relay , they go bad also.
