If you put "Diagnostix" in the ELB search box, you should find alot of info on the lightbar. If you're into geeky details, you might find this thread interesting: https://elightbars.org/forums/threads/edge-9000-not-powering.94107 HTH

Can I assume your #230 controller doesn't make your lightbar do what you want? I.e. you have all red lenses in front...not much point in seeing red take-downs/steady. Do you have red lenses all the way around (do you have alley and rear halogen lights? Are they red-lens too?) Is that piercer a...

If you still have it, I'd be happy to buy it off ya! but would be very disappointed to find it to contain parts made in 1967

Last page of a 1978 aircraft "CATALOG E" (courtesy of @JohnMarcson): Please note this part: If there's any evidence of a viable Whelen PS presented to the market place prior to '67. I would _love_ to hear about it.

If you have any evidence you can share, that Whelen offered a strobe in any form prior to 1967, I for one would be _extremely_ curious to learn more about it. So as not to hijack this thread, please post to this thread. Thanks!

Nice find! That mysterious device you pictured is a "spark-gap". It's a nice down-and-dirty "timing trigger " device as when the voltage across it reaches a certain point (likely ~230V) it sparks, shorting the trigger cap and causing the flash. Here's a vid of one in an old Whelen PS with one...

For context, see this thread: https://elightbars.org/forums/threads/whelen-blink-b-link-serial-thread.5914/ I've purchased a few MCP01s in the past few years within a price range of $90 to $30. The $90 unit came with a promise from the seller to program it for my lightbar at the time. I'd...

for an MPC03? (USB-enabled)

The explains basic wiring: https://www.whelen.com/wp-content/uploads/2020/08/13993.pdf As far as programming, I suggest reaching out to jperrylighting.com to ask him to program it for you, or post a WANTED here on ELB requesting a service. if you want to program itself, you'd need: 1) The...

Any one of the three (MPC01 or MPC02 or MPC03) will work. They all will do the same thing w/r/t to making the lightbar work. My understanding is that: MPC01 has an audio interface (i.e. Microphone/radio-repeat) - MPC02 does not -- they both require a serial interface to program them. MPC03 has...

You can use the controller you have with any "WeCan" bar (not "WeCanX") - you can browse Whelen's website to see examples of what they're making today and get specific model numbers. Just click on the "MODELS" to get the exact model numbers that do "WeCan". There are a ton of them in the...

Okay, that confirms @shues 's assessment. You have a "B-LINK" serial-controlled bar. You'd need an MPC01 (or MPC02 or MPC03) controller and get it programmed to work with the bar you have. You can program it yourself but it can be tricky. The programming software "SC Programmer" is still...

How many conductors do you see in the smaller black cable coming out of the lightbar? If only two, then as shues mentions, you have a "serial controlled" lightbar. "serial controlled" aka "B-LINK" preceded WeCan. B-LINK was based on RS485, an electrical standard for serial communications. WeCan...

Thanks for reporting back! Its too bad they couldn't be made to work together but at least we know.

Might be a red-herring but here goes: This reminds me of when I tried to use a CenCom Sapphire ca. 2012 with a Legacy ca. 2018. In this case, the CenCom would try to talk to the Legacy over CanBus (Wecan) but didn't understand what the Legacy sent back. I reached out to Whelen's tech support and...

I have no experience or affiliation with them but you could possibly try: https://www.radwell.com/en-US/Services/Repair Under "Category", pick "Lighting" then under "Sub-category", pick "Strobe light".

I'm using: https://www.nichicon.co.jp/english/products/pdf/aluminum.pdf as a source of information. It states, "The DC voltage that is applied to the foil to oxidize the anode foil is called "Forming Voltage". The thickness of the dielectric is proportional to the forming voltage and measures...

Perhaps you were remembering @dmathieu's post here?: https://elightbars.org/forums/threads/question-about-older-powersupplies.36338/post-329317 It does state that flash tubes should be removed but it looks like Whelen changed that part of the recommendation at some point (they also added the...

Quoting from page 45 here: https://www.csobeech.com/files/WhelenInstallManual.pdf "WARNING: Strobe light power supplies are meant to be used, not to remain in an inactive state. Use them at all times, this will improve their proper functioning. Any strobe light power supply that has been out of...

The VPPS6C is potted, right? I don't think there's much chance of repairing it, unfortunately.

Could you maybe get some pics of the underside? I'm guessing the primary capacitors are original and will need to be reformed. Checkout page 45 here: https://www.csobeech.com/files/WhelenInstallManual.pdf for Whelen's recommendations. You need to give those caps some exercise but you do _not_...

That's an intriguing questions but I'm sorry to say I don't know the answer. We know lenses for incandescent/halogen light sources are designed around a pretty tight focal point. Strobe flashtubes don't have a single focal point and there are a few different flashtube shapes in play here so I'd...

That pic of light cast from an incandescent lamp in the "optically corrected" clear lens is at the bottom of this post: https://elightbars.org/forums/threads/gen-1-whelen-commander-glass-internal-optics-possible-origin-story.95590/post-692091 If you stand about 20 feet away at the horizontal...

No single voltage number can be used to indicate charge state because different discharge rates (loads) produce different under-load voltage curves over time...ie: Given a fixed load, we can at least use this chart to "ballpark" an under-load voltage measurement. Still, it seems to me (from...

Thanks for testing! I predicted ~12.00V @ 5 hours but I was off a bit. Though really zooming into the blurry charts shows the crossing point to be a little higher than 12.00V. For the sake of battery life, the depth of discharge should be as shallow as possible: Not sure I helped much but I...

Thanks for trying...no worries.

This is a pure guess based on the blurry chart (and nudging the numbers on the graph hoping to line them up better -- I hope I got them right): and I'm not sure this even makes intuitive sense...but it if we use the curve closest to the 3amp load goal, we'd expect about 12V (2.00 V per cell) at...

w/r/t amps vs watts charts, check out: https://www.bigmessowires.com/2020/03/17/constant-power-battery-discharge/ The per-cell watts number (39.7) needs to be multiplied by 6 (cells in a 12V battery) to be comparable. I also found...
