Re: flourescent ballast resistance

Re: flourescent ballast resistance

For what it’s worth, GE still makes magnetic ballasts for the NA market. I thought nobody made those magnetic ballasts anymore?

Interesting light fixture. There is not much room inside. I’d be...

Re: flourescent ballast resistance

The one I dealt with had always turn on / flickering problems. The magnetic ballast would be getting so hot, I had to cut a piece of the AC cable off as the insulation would fall off and black stuff...

Re: flourescent ballast resistance

Re: Turbo Start QPET 16V/25A racing charger repair

Turns out the SCR's are actually O.k. when tested with my bench PSU. The DMM and another component tester didn't have enough oomph to trigger the gate. :smack:

Problem was in the wiring. A chaffed...

Re: Short finder

Looks like a similar idea to the Leakseeker 89, just with a display instead of a row of LEDs and sound.

Re: Turbo Start QPET 16V/25A racing charger repair

Yes, this charger isn’t that dumb. It’s also got a timer IC in there. The parts in the gate drive are good, just both SCR’s are shorted cathode to gate leaving the anode wide open. There is a trimpot...

Re: Why would an HP deskjet not print?

The last ink printer I bought was over 25 years ago. They had issues back then and they still work like shit now.

Re: Reebok one GT40s treadmill lift motor runs at switch on

I guess these things are known for the incline needing to be recalibrated. Google “Reebok get40s incline calibration”.

Re: Turbo Start QPET 16V/25A racing charger repair

Ordered some Little Fuse S4035JTP SCR 400V 35A TO218X with isolated tabs. That should do the trick. Didn't find anything wrong with the components on the Gate.

Re: Fluke 289 bad supercapacitor replacement repair

Yeah... I figured that out too that 10.5mm diameter is the biggest that fits in there.
Panasonic EECS0HD334H has been discontinued long time ago. :facepalm: I came up with a Eaton KR-5R5H474-R....

Re: Fluke 289 bad supercapacitor replacement repair

I looked at those and they aren't available for me. Meanwhile I needed to do up an order and today they pushed the date back 2 months. Hmm... back to square one.

Re: Turbo Start QPET 16V/25A racing charger repair

HIS235 translates to SCR 200V 35A. It should be Cathode, Anode, Gate. Both SCR’s are shorted cathode to gate (pin 1 to 3). The tab and anode (middle pin 2) are wide open. The case style is a TOP3....

Turbo Start QPET 16V/25A racing charger repair

Another weird charger. Didn’t even know that there is a 16V AGM battery. I guess that’s what racing guys use and it’s quite the complicated thing looking at the inside of it. Never have seen a...

Re: Fluke 289 bad supercapacitor replacement repair

Last time I replaced it with an ELNA DSK-3R3H224U-HL. BTW this part number is still current. Mouser and Digikey have them on back order. So it may be good to wait if time is reasonable. It's about...

Re: Fluke 289 bad supercapacitor replacement repair

Re: Fluke 289 bad supercapacitor replacement repair

Re: Fluke 289 bad supercapacitor replacement repair

If you take the battery out, wait a minute and put the battery back in and the 289 lost time and date, good chance that the supercap is leaking physically. A new supercap held the time and date for 3...
