Re: Fluke 23 Fusible Resistor

The Fluke 70 series I is grey. As I understand it, Fluke took the 70 series I and added better probes and made the case yellow for the Fluke 20 series I.

That's why I referenced the Fluke series...

Re: Fluke 23 Fusible Resistor

RT1 is close by C1. See page 7-2 on Fluke 70 service manual.

Re: Fluke 23 Fusible Resistor

No.

A spark gap should measure open circuit resistance.

Re: Fluke 23 Fusible Resistor

If you made an "oops" moment, you need to check all the input protection components for damage. While some may be obvious, others are not.

1. All your MOVs should measure 0L in resistance mode....

Re: Alternative Browsers for older machines

If you are determined to use these old motherboards, try to find it's fastest supported CPU. You can probably get them on ebay for $5 or less.

I gave up on single core 32 bit systems for watching youtube around 7 years ago. When I watched a 360p video on a socket 478, CPU was at 100% and multitasking was impossible.

Re: Help with car battery charger HT7715

BTW, the PCB was made 2010 03 02 so it's 10 years old.

If the startup cap was cheap quality to begin with, I can see it failing/dried out even without much usage.

Re: Help with car battery charger HT7715

On the back of the PCB, one of those larger ICs should be the SMPS chip.

If you look at its part number and find the datasheet, it will tell you what the typical VCC startup voltage should be.

Re: Why Lubuntu?

X or L, it really doesn't matter.

I chose L back in 2014, because it used less resources than X. Back in 2014, I was still using P4 and low end dual cores with only 1GB DRAM so I had to be very...

Re: Help with car battery charger HT7715

A low clicking noise might suggest the power supply is trying to start, but the startup capacitor is bad or dried out as stj suggested.

A dried out cap won't show any obvious signs of damage.

Re: Desktop EMachines ET1331G, AMD Athlon(tm) II X2 250u Processor

Xubuntu is a good choice. I use Lubuntu.

Version 20.04 will be coming out late April 2020.

X/Lubuntu will run on 1GB DRAM, but 2GB is better with today's browser.
