Hi,

A bit late, but I'll give it a try.
You can measure the outputsignal before the relay.
Often there's a coil, measure if you've got a DC level at that point.
If so, you're power amp is down.
Normally when the relay doesn't switch there's a DC level in your amp.

Cheers, Gerard

How do you test the three relays to the radiator fan on a 1995 Mercury Villager?


When you apply power and relay clicks,that means its good.Best way to test relay issue is swap the relay with another working relay of same type and see if problem goes.This relay issues are very frustrating,while testing it shows good but still it will not work sometimes and after replacing relay all gets good.Also relays are not costly to replace.You can try swapping the relays and see if it helps.

I have 2 Peavey Impact 1015s and 2 PV 118 Subs. I have a Peavey Kosmos PRO that runs from my Numark CDMix3 to my amps. My two amps that I have are a Peavey CS800x and a Crest Audio CD3000. Could you tell...


Just a note regarding connecting: USE BALANCED lines everywhere you can. Use either XLR if available or TRS type cables. This will reduce noise pickup.

Another hint: For SAFETY of your equipment run ANY interconnected devices from the SAME power source. DO NOT say power the amps from one place and your other equipment from a different outlet. Afford a power distribution system that feeds from a single receptacle or nearby receptacles near a common electrical panel. This will ALSO help avoid noise as well as the hazards to your equipment from ground loops.

The DDT light on one channel stays on,but I can't find a reason why? What can I do?


Disconnect the speaker wiring and speaker on the bad channel. Turn the level control(s) all the way counterclockwise and turn the amp on. If your DDT (limiting) light remains lit, it's time for a visit to your nearest certified Peavey service center....G.

Peavey CS-800 PA power amp 1 channel is out


Hi Bill,

It's a log time ago that I repaired those amps., but I give it a shot.
There's a speakerprotection after the finals, what I remember it's a triac (SAC187, or something like that).
You will find it at a small pcb at the back of the amp. Normally it has three legs but the centre is cut away. If it's down you will measure 0 Ohm at the output, also with a switched off amp.

Thats all I can remember, it was about 25 years ago.

Maybe it helps,
Gerard
