Poineer deck amplifier dc-z74 relays click but set deck does not come on no display lights dead unit


Part of your PowerSupply is Frito.
Probably the +/- 15 volt rails, could be other.
Check inside power voltages, probably some regulators are gone.
Preferably get a tech unless you have the know-how and test equipment...

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

Motorcycle Mechanic Advice on a 1992 Heritage softail. Having ignition problems. Lights come on and I get a clicking in the starter relay, but when I switch it to ignition, there it is completly dead....


I'm a little confused. You said that the lights come on and you get a clicking at the starter relay. Then you say that when you switch to igniton, everything goes dead. From the factory, you must first turn the switch to the ignition position before you can get anything, lights, starter, horn. Some guys set their switches up to be like an old style bike. First click is ignition, second click is ignition and lights. But, since most states now require you ride with your headlight on all the time, Harley simply wires the switch to a "one position" switch.

At first guess, I'd think you have a bad switch because you said the when you went to the "ignition" position, everything went dead.

But, you said that you could get lights and a clicking noise. If the clicking is coming from the small one inch plastic cube starter relay, you may or may not be getting power to the starter solenoid.

Look at the starter from the right side of the bike and you'll see a five sided plate with three small bolts holding on. At the top of this plate, you'll see a single wire connector. Unplug this wire and use either a test light or a volt meter to test for voltage on this wire when you press the start button and the starter relay clicks. If you do, the relay is good but something is wrong in the starter. If no voltage, the relay is not doing it's job.

Good Luck
Steve

Your belt is likely broken. Pop the top (held down by spring clips) to inspect. If you see it - try to lift it. If you can not lift it it is ok. If not ok, remove the front cover for complete access to the drive.

Sony tv wont turn on, standby light just flashes


check for an open resistor on the power supply, it is actually a fusible resistor, (white) if open, then check the converter, some sets have two separate and some have it as one. it will be on a heat sink on the power supply. if shorted then check for a shorted horizontal output transistor and repair cold solder joints on the horizintal drive transformer which is the real cause of this problem
