Bob,

I was making my third flight in my Tri Q 200 this past Sat. I noticed that

every time I presses the mic remote key switch, the OV light would come on.

Nothing is connected to ships power at this time. Using nine volt on

intercom, and a new IC-A6 with it's own battery. Ever heard of anything like

this before? I did not have the ships antenna hooked up either. Rubber ducky

only.

I did not notice it on the first two flights, but may have not been aware of

it. Had other tasks on my mind.

Thanks for all you do.

   At first blush, it sounds like the OV sensor is sensitive

   to RF.  Hand-helds with rubber duck antennas can be the

   worst antagonists with respect to cockpit mounted accessories.

   In fact, I used my hand-held as a quick-looksee for RF susceptibility

   for hardware on the bench.

Dang, I was expecting to read something interesting about applied fluorescence technology or day-glo instruments in the cockpit...  apparently the UV in the header is actually OV?? 

do not archive

 Who's OV light?

B&C Specilaties.

The light comes on steady when the mic is keyed.

Today, while doing a cowl off inspection, I noticed that the small stranded

wire from the large post to the small post on the S701-1 contactor was

burned in two. I did have a OV trip a few months back while taxi testing,

but figured it was a nuisance trip. Without the small wire the alternator

has been functioning. The battery seems to have full charge. Did not use

tester it was at home. Just looked at the volt meter. Turning the master on

did not bring up the LV sensor light.

 At first blush, it sounds like the OV sensor is sensitive

 to RF. That is what we thought also but I was curious.     Hand-helds with

rubber duck antennas can be the

Bob,

I will try this again. The first time I tried to snip. Didn't work.

The OV/UV sensor came from B&C.

The light comes on steady when the mic is keyed. We aslo thought if might be

RF.

Today, while doing a cowl off inspection, I noticed that the small stranded

wire from the large post to the small post on the S701-1 over voltage

dissconnect contactor was burned in two. I did have a OV trip a few months

back while taxi testing, but figured it was a nuisance trip. Without the

small wire the alternator has been functioning. The battery seems to have

full charge. Did not use a tester it was at home. Just looked at the

voltmeter. Turning the master on did not bring up the LV sensor light.

Any ideas?

Check your wiring.  When I turn on the master without the engine 

running/alternator producing energy, the LV light is blinking.  I can also 

get the LV light to blink at low rpms with heavy load, i.e., all the lights 

on ( I have an 30 amp alt.)



If your wiring checks out, I'd call B&C to see what they think about 

possibilities that you have a bad regulator.

Thanks for the reply.

The documentaion that came with my unit states " A flashing light indicates

a bus voltage greater than 15.5 volts DC. Steady light indicates bus voltage

below 12.5 volts DC."

Mine too will ack as yours at low RPM. Must be just at the LV set or below.

Increasing 50 RPM or so will make it disappear.
