How do you know you're getting an OV event . . . tripping of the B&C crowbar module? >Bob one other thing I've noticed is your diagrams call for a 22Kuf >capacitor in the over voltage protection circuit but what I got from >B&C when I bought the package was a 10KuF capacitor, would this have >any bearing on this over voltage condition. No. Describe events leading up to a trip. Does it run for a time and then trip when you DO something or does it trip at random? What is your bus voltage for normal operating conditions? Have you bench tested the OV module to confirm it's calibration? We set them for 16.3 +/- 0.2 volts at room temperature. It is doubtful that battery has anything to do with it.

Yeah, I don't usually use their substandard stuff but this one was designed and built to Rigid's specs and Rigid has a good, long reputation. My particular one appears to no longer be available but it has saved me more grief (and money) over the past few years that is has paid for itself at least 200 times in saved contractor and engine costs. I use it for the house, vehicles and just about everything. Ironically, it won't do the primary job I bought it for, looking down into the air filter Deeply embedded in a Honda GoldWing 1800. The camera end is just too big and it's only about 3/8 inch or so. It takes over an hour to take enough of the Wing apart just to inspect, let alone replace, the air filter, then another 45 minutes to put all the plastic back together. I think I'm talking about a different tool but the same jobs that you're seeking answers to, Paul.

They also post customer reviews for every product. They also guarantee their products, but veteran Deal Extreme buyers know that--on balance--it's cheaper just to take your chances. While you're at it, buy their Cree LED flashlights (and don't go too cheap...the more expensive ones are astonishing). And don't forget their HIDs, household LED bulbs...it's endless. For any of their stuff you can't can't can't possibly beat their prices. I bought their 4X USB PCI/NEC Card for my Computer. $5.30...FREE SHIPPING (when I bought it, the price was $4.19). Somebody slap me and wake me up.... You CAN buy stuff that is pretty poor quality (but ridiculously low price) from them, but read the reviews first and then decide. If I put together some landing lights, almost all the key parts will come from them. I bought several big condenser lenses, and as one who is used to really first rate optics....I was simply astonished at how good they were. -------- Eric M.

The coax is presently unused and surplus. OR any better ideas?? Does your hand held have a VOR-LOC function that you'd like to exploit? The wingtip VOR antenna is best suited to horizontally polarized VOR/LOC signals. It will function on comm service but with degraded performance. Even so, the external VOR antenna may be a better COMM antenna than the rubber-duck used from within the cabin. There's no risks in giving it a try. You can go to plan-B if your experiments are disappointing. Consider this option. Bone up on antennas in general here http://aeroelectric.com/articles/Antennas/Antennas_for_Aircraft.pdf http://aeroelectric.com/articles/Antennas/Popular_Antenna_Lore.pdf Then consider hammering something like this together . . . http://aeroelectric.com/articles/Antennas/DIY_Comm_Ant/DIY_Comm.html But if your wingtip VOR proves adequate to your needs, you're good to go.

Good question. The 3-terminal regulators are self-current limiting so a shorted h-bridge wouldn't open a fuse. Further, the h-bridge is so lightly loaded and protected from external antagonisms less than lightning strike so I think that worry is insignificantly small. >What about integrating a "master disconnect" pulse from an external >push button ? If the trim system associated with this controller were capable of putting the crew in a high pucker-factor situation, it would probably be something to consider. But if anyone's trim system is aerodynamically risky if run to a stop, it's probably wise to fix the set up as opposed to adding a crew operated disconnect.

It came with some small accessories like a mirror and magnet for the camera end. I also purchased the 1 meter extension. Unfortunately, it didn't work for the purpose purchased, to see down the filler and into the fuel tank. It hangs up somewhere on the aluminum section. But otherwise it has proven to be very useful for inspection in difficult to reach and see places. Matter of fact, I have it in the truck ready to take on the next excursion to the hanger for use in the annual. I have used it and the magnet to retrieve bits from difficult locations. I have used it to locate dropped parts. I don't remember the cost, but it was quite reasonable. It doesn't have any recording capability though. The price really goes up when you add the ability to record. Good luck. Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop.

I know I'm getting an over voltage event because is trips the 5 amp breaker in the over voltage circuit and it's hot to the touch, plus I can see the voltage increase on the EFIS most of the time, otherwise reviewing the recorded EFIS data (1 second increments) This happened once early in phase 1 but has progressed to where it will happen multiple times per flight now. If I keep the landing lights on I can prevent the event. One curious change, it used to take a few minutes for the breaker to cool off before it would reset. Since I moved the yellow IGN wire from the OV relay to the battery positive terminal when the voltage increases and trips the OMV I can toggle the alternator switch and immediately bring the alternator back online. I have replaced the OVM14 and the voltage regulator and haven't eliminated the problem. Any help would be appreciated.

Make sure the regulator is well grounded. I suggest monitoring the voltage between the voltage regulator metal case and the 18awg yellow voltage-sense wire where it connects to the regulator. If that voltage goes above 14.5 volts, then replace the voltage regulator, regardless if it is new or not.
