Re: Repair Fence Energizer SS-1000E Fi-Shock

don't need to match if in series, just like LEDs. However if dealing with reverse voltage they may need to be treated like capacitors and deal with the leak caused by the balancing...

Re: Repair Fence Energizer SS-1000E Fi-Shock

BTW, when we say that capacitor is leaky, we mean EPR or effective parallel resistance, not ESR. Simply use a regular ohmmeter (DC ohmmeter, not AC ohmmeter which is used for ESR) with the probes in...

Re: Repair Fence Energizer SS-1000E Fi-Shock

yeah, diodes seem like they've seen better days. Even vacuum tube diodes have near infinite reverse resistance.

Now what caused the diodes to go bad... Better make sure the big cap didn't go...

Re: Repair Fence Energizer SS-1000E Fi-Shock

if the 360Ω resistors still heats up with the transformer disconnected, only thing that could be causing it is a shorted main filter cap...?

Re: Repair Fence Energizer SS-1000E Fi-Shock

Well you can still do tests quick before it starts smoking.

Is it still generating high voltage?

Now it seems that the trigger circuit is stuck on perhaps. Does it still heat up when the 2M...

All three, Bigclive, DiodeGoneWild, and ElectroBoom have nutty videos...

That second one clip has an age restriction on it too. I'm going to pass on it though I thought I seen it before (meaning,...

No, no no...We don't need Bigclive to test one. We need ElectroBOOM to test one :D

Re: Repair Fence Energizer SS-1000E Fi-Shock

Keep in mind, 600KΩ is near the resistance of sweaty human fingertips from hand to hand, and that's why it's dangerous to touch live voltages...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Probably safer to replace one at a time since you're dealing with not-exact matches.

Anyway no point in replacing the other resistor - resistors usually aren't 'wear' items unlike capacitors...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Well, I guess measuring the voltage is easier than desoldering and measuring resistance anyway :) We found the bad resistor without a soldering iron!

You can probably substitute something close...

Re: Repair Fence Energizer SS-1000E Fi-Shock

It won't get to 2 amps sustained, don't worry about it. Peak, maybe; but not sustained.

Other things would fail first if 2 amps flowed through continuously...

Re: Repair Fence Energizer SS-1000E Fi-Shock

How about this:

what's the voltage across the power resistors 32->33 and 26->27

They better be fairly low unless the resistor is burning up hot.

Might well also take the voltage across 2->3...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Wait, the big capacitor should charge up to full DC voltage fairly quickly - should be well over 100 volts within a few seconds. If this is not the case we have a problem there - look at R1, R2, and...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Though 2M * 22F is large (44 seconds), getting to 30V in 30 minutes is way too long. Either that 2M resistor has gone open or something is leaking the charge off the capacitor, and it could be the...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Testing the coil requires specialized hardware, known as a ring tester. I haven't seen many coils go bad however without some serious overheating. But it looks like you do have an LCR meter which...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Might be a measurement problem, RMS voltage, etc. If it were really 50V, the two 10W resistors would be roasting or roasted in the past to burn open.

As for testing the DB3 I don't think most...

Re: Repair Fence Energizer SS-1000E Fi-Shock

Never build RC timers with electrolytic capacitors... at least if you want repeatability.

Now that you're forced to have one, choose least leaky capacitors. I'd say you should definitely use 100V...

Re: Repair Fence Energizer SS-1000E Fi-Shock

I was guessing C2 as bad as if it were leaky it could also never trigger...but that would somewhat be a wild guess.

It is worth to test if the SCR is still good. If you have a 12V PSU, a small...

Re: Repair Fence Energizer SS-1000E Fi-Shock

How about this guess: replace C2, seems this could cause it to no longer oscillate.

Maybe this is a badcaps problem after all? :D
