You can safely discharge the capacitors by using a piece of insulated wire with the ends bared a little an putting one end of the wire on each terminal of the capacitor to drain it causing a temporary short to discharge it

My 2003 honda accord v6 refuses to start. It cranks but no spark on the plug. What should i do?


Either the spark plug is faulty or the coil pack is faulty.The spark plugs get power to spark from coil packs.

If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).

But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to spark plugs or hairline cracks in the coil output tower.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.----------This should help.Thanks.Helpmech.

I have an electrical problem and need some help. The other day I was riding and I flipped the headlight switch to high beam, the engine began to miss and then it completly shut down, we used jumper cables...


Yes, I suggest that you are not charging properly. the headlight to high beam killing in one instance and no effect later is the big clue. You were riding along, slowly loosing state of charge, and it was not apparent, then place heavier load, and the system does not have the voltage to run everything....so the rough, etc.
So, where are you? You need to independantly slow charge the battery. check water, and connection quality. this charge, on a home charger needs to be like 2 days or so...if it boils, get another battery or be mislead in other tests. batterys that boil do not make it, ultimately, and leave you stranded.
Then put the battery back in the bike, hook everything up, start up and at 1500 to 2000, measure voltage at the battery. Needs to be 13.8 to 14.2 or pretty close to that.

Bikes tend to overcharge batterys. This boils out the water, and cells goe dry and that kills battery, just replace it.

A common issue with bikes is the DIODE PACK, to make an alternator work DC on 12 volt systems, diodes are required. They are one way valves for electricity, and fail often. Then you have a leak to ground and the battery goes dead, as well you do not charge correctly, same leak.

Easy to change, measured with a scope, (yeah sure) or ohm meter. Continuity test, go one way no go the other. Any open, or connect in both measurements is failed.

My bet, diodes...And get a Harley. Just kidding, but you do get to know all of this stuff with a Harley, cause they always break...

Where is the power supply on model #42pfp5332d/37?


Hi

You can obtain service documents for this TV from
https://www.manualsparadise.com/ShowProductsForModel.do?model=M53646572

I do not have the service manual for this Plasma TV myself, but it is not difficult to locate the power supply inside the TV, follow the power cord, when it goes into a board, you know that is the board, most likely has high voltage components 400V and similar, you can't miss it.

Don't touch what you don't need to touch, you might shock yourself or in worst case, injure yourself or get killed.

NEVER OPEN A UNIT WHILE ITS PLUGGED IN; UNPLUG AND LET THE SET SIT FOR AT LEAST A HOUR. and even then, the components - capacitors may hold even deadly voltages.

Not draining


These machines are so touch when it comes to the drain. If the screen is dirty or there is clog in the pipes. The machine gets an error and stops rinse/drain cycle.

After cleaning and inspecting the drain system and by chance the problem persists, you need to to test the voltage and resistance from the main boar and any sensors.

50' rca projection tv


your high voltage splitter is probably bad, or you high voltage flyback transformer (deflection board). not sure of your model #, is it correct? It may be a lamp but you shouldnt smell burning. You can unplug and let it discharge and find where the burnt up parts are to find your problem. Follow your nose, it always knows!

High-voltage can hurt/kill you.. be very careful

Toshiba 42 " TV


This is a sign that there is a problem in your high voltage section of your TV. The anode voltage might be dropping to a lower then normal level. This would cause this problem. I would suggest that you not try to repair this yourself becausee of the dangerous voltages that are present in the high voltage section of the TV set. You may have to take this set to a qualified electronics repair shop near you. I know this is not wha you want to hear, but the voltages involved can kill.

Power surge


If your not a technician with tv repair experience, I would HIGHLY advise against that as theres high voltage in these sets even if they have been unplugged for awhile. Enough to kill ya. First thing though that comes to mind would be the STR##### regulator IC in the main power supply. That usually goes bad when a surge happens. But call a pro, Bro. Good Luck
