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.

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....

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

I measured around for shorts / opens. Well... those HIS235's are bad. I took both of them out and they have a failed in a strange way. The center pin isn't connected to the tab. Both outer pins are...

Turbo Start QPET 16V/25A racing charger repair

Another weird charger. Didnít even know that there is a 16V AGM battery. I guess thatís what racing guys use and itís 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

I charged my batteries for one hour and I've lost the memory. Set time and date appeared again. So my supercap that I replaced in 2018 went bad again.
I did look at the newer 289's and they have a...

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...

Turn the backlights away down like less than 50% and see if they stay on longer.

Re: Sony STR-DN1030 Distorted audio when Volume adjusted

As a last ditch effort, you can heat with wifeys hair dryer or freeze the IC400 taking a can of air upside down. Other than that, I’d be giving up and either replace the IC on the board. You did...

Re: samsung le37c630k1w standby lights but no power on

Missing PSon is most of the time a problem with the mainboard’s main IC. Nothing much you can do about it besides replacing either the board or the IC.
