M20TN_Driver Posted June 29, 2022 Report Posted June 29, 2022 I will start the thread by saying I have only owned this plane for 3 years and do not have a shop manual for it. So I am probably asking questions that I shoudn't be ;-) However I found during on inspection that the right wingtip strobe was out on my bird. Nav lights work fine. Left, and Tail strobe work fine. I have tried a new strobe in the right wing but determined that it is not the bulb...both the new strobe bulb that I installed and the existing strobe bulb work in the left wingtip. So then I went to the power supply mounted on the pilot side avionics bay bulkhead and it is also not the problem...swapped it out...same issue. I noticed that there is also a Whelen power supply in the tail that looks to be just for the tail strobe--it works. So my question is this: Is there another power supply in each wing dedicated to each strobe? Is there one in the right wing somewhere that might be the issue? I'm not sure where to go from here. The folks at Savvy are telling me there is one per strobe. So no clue where the one would be mounted for the right wingtip. I looked at the inspection panels under right wing (there are a ton of them) and none had additional screw mounts for holding a power supply. Sooo, I thought I would ask this extremely knowledgeable group on where I should start. All help appreciated. The pics below are the two I found--both working as they should. Quote

M20TN_Driver Posted June 29, 2022 Author Report Posted June 29, 2022 Oh boy. That's what I was afraid of. My concern is that I now have a wiring issue between the bulkhead and the right wing... Quote

My concern is that I now have a wiring issue between the bulkhead and the right wing... I doubt it, it's almost always the power supply. Even though you may show power it might not be enough to activate the strobe. Mine work fine, but on my list of future upgrades is to replace the strobes and nav lights with the Whelen LEDs that are on the Acclaim Ultras. No troublesome power supplies. https://www.dropbox.com/s/bi0xi52kn5d3v84/Acclaim Ultra Strobe.JPG?dl=0 I upgraded to LEDs on a Bravo and it was trouble-free. Quote
M20TN_Driver Posted June 29, 2022 Author Report Posted June 29, 2022 (edited) I swapped the power supply out with another identical unit and had the exact same issue so not thinking that both Power supplies would have the exact same problem... Love the LED for sure... Edited June 29, 2022 by M20TN_Driver Quote

Love the LED for sure... Had you personally seen this power supply working in another airplane? In other words. was this a known-working power supply or one that someone took out of their airplane and was selling used? People take them out when they are weak and when they decide to go to LEDs.

M20TN_Driver Posted June 29, 2022 Author Report Posted June 29, 2022 Well that is true. It was a guaranteed to be working unit…bench tested with a yellow tag. But who knows. Maybe it wasn’t. I’m going to switch the leads on the power supply from the right side to the left side and see if that works. If so, then I know one side is dead and one isn’t. Quote

M20TN_Driver Posted June 30, 2022 Author Report Posted June 30, 2022 Who did your LED setup? Are you then able to remove the Whelen power supplies or are these drop in replacements to the existing lamps only? Quote

Power supplies and the 2.1 pounds a piece come out and it is direct wire - LEDs just use the 28volts. I didn’t sync mine but I think the way that the Acclaim is wired would make the sync easier. I definitely wanna do my Acclaim. These should be the ones you need: Whelen OR6002R (Red LEDPosition Light, LED Strobe and White LED rear facing Position Light) Whelen OR6002G (Green LEDPosition Light, LED Strobe and White LED rear facing Position Light) Whelen 5002V (Tail light LEDstrobe and white LED position light Quote

They're just in a box in my hanger if you want them. Quote
M20TN_Driver Posted July 4, 2022 Author Report Posted July 4, 2022 Thanks for that. Very kind. If I determine it’s actually the power supply, I’d love to take you up on that offer ;-) 1 Quote
LANCECASPER Posted July 4, 2022 Report Posted July 4, 2022 Unfortunately the Bravo used one power supply for each wingtip strobe. The Acclaim uses one in the avionics bay in the tail for both wingtips. Quote

M20TN_Driver Posted September 28, 2022 Author Report Posted September 28, 2022 Ended up being a bad wire to the left wingtip. Ended up swapping out the whole setup for LED and have now posted the complete lighting package removed from the Acclaim in the classified on the site. Thanks you all for the help/guidance. 2 Quote

AZOutlaw Posted December 9, 2022 Report Posted December 9, 2022 @LANCECASPERI've been told, and you mentioned, that the power supply gets removed when going to LED's. I assume the wiring connects where the Power supply is removed, right? I can't seem to get a wiring diagram but would guess that the + and - inputs connect to the outputs and one of the outputs is the sync, which connect together. Quote

stevesm20b Posted December 10, 2022 Report Posted December 10, 2022 My wingtip strobe power supply went out in my 81 231. I found I could replace both wingtip strobes and nav lights with the Whelen Orion 650E LED wingtip position/anti-collision lights for just a little more money than what just one power supply costs.

Yes i agree the power supplies have priced themselves out of being viable unless you are going all original equipment it doesn’t make economic since to replace The power supply especially when the life expectancy of LED is sooo much longer. 1 Quote

The Acclaim only had two. Thankfully the weight is printed right on the box. Quote
peterl Posted December 11, 2022 Report Posted December 11, 2022 I only found one power supply in my acclaim on the lefthand wall in the avionics bay supplying the wingtips. Where is the box located supplying the tail strobe? Quote
