No lights or power indication at all on my DMR-85HP.
No lights or power indication at all. I pulled the cover and the fuse checked good. When I put the HD back in and applied power I believe that I heard a hum (like it was powering up and self checking) from the HD, but still no lights or other indication.
Re: no lights or power indication at all on my DMR-85HP.
I had same problem - No Power/No Display. I replaced two bad capacitors on the power supply
card. See http://vassfamily.net/projects/DMRE85H/dmre85h.html The
capacitors I replaced were C1260 and C1261 slightly different from the
one on "vassfamily.net". Everything works now for me...
If replacing the capacitors doesn't work, try replacing PSU Regulator - STRG6353.
for those interested, I found the "commands" listed on
http://www.dxcc.com/dmr-e85h.htm useful when operating the DMR-e85h to

You may have 2 separate problems so I'd try to approach it that way. RADIO - On this older truck, it may be that there is a separate in-line fuse for the radio. If you can see under the dash where the wires come from the radio, look for a red or black one that has an in-line fuse holder. Push the ends inwards and twist counterclockwise, then pull apart to get at the fuse. It is also possible that the "accessory" terminal of the ignition switch is no longer working. A continuity meter should help you resolve that.
DOME LIGHT - Pull the bulb and test to make sure it's working. Check for power at the bulb connection receptacle (socket). Dome lights typically are switched from the doors or by rotating the light switch. If the bulb is good, it should be a hide and seek game to find where the power is, and where it isn't. The shorter the distance between these points, the closer you are to the problem.
Patience, and a sense of humour. You'll get it.
Do you have a test light? If you do, ground it and probe all fuses with the key in ON, not start, and with the indicator turned to one side or the other. The fuse that blinks the test light is the indicator fuse. All the other fuses will have a steady light on the tester. With key on, all fuses should have power to and through them.
The tops of all fuses have two slots on the top-one at each end. these are test ports and open to the metal strip inside the fuse. Touch the needle probe of a test light into one of the slots. With key on, it should light up the tester. A good fuse will light the tester at both ends, both slots of the fuse. But a blown fuse will light up a tester at only one end of the fuse-the power into the fuse, but no power on the other end of the fuse- the metal strip has blown apart and the fuse will not pass power. You can check any fuse this way, without pulling the fuse out to investigate.
Check your "GROUNDS" first. Or you could try this. Under the hood you will find another fuse box with non-typical looking fuses. I believe there is a main fuse in this box. The box itself is probably located on either side-wall, (over the fender) should have a plastic cover over it. I would pull this cover off and look for the "main" fuse and pull it. if you have a light-tester or a multi-meter, check if you have power to here. I have to run for now good luck. 1976 huh? Cool Van-man!!!
First: Check the light to see if it is good. If bad replace and check again. Put light in another location to check it.
Two: if light is good, check wiring and make sure it is connected properly to the junctions it is supposed to go to.
Third: If all of the above are good and it still does not work; Check to see if it is on a separate fuse and replace if necessary.
hi, if all the fuses are ok and you have no indicator lights at all then the problem is going to be the indicator relay this is either located in the fuse box or under the dashboard it is what you hear clicking when the indicators are working ok now they put them in different places on all cars some makes its in the fuse others it under neath the dashboard usually behind the cowling covering steering coloumn if you purchase one first you will then know what you are looking for they just push in and pull out so are easy to replace. If you ask them at the place you buy it from they should be able to give you a good idea where this is located. It looks like a square box about the size of a match box they are different colors once you have replaced this you should have all the lights working. Hope this is some help tp you let me know if you need further assistance ok
The chances are that you bridged the printed track with a splash of solder when you replaced the regulator. A short circuit like this will cause the fuse to blow. You can get replacement 20mm slow blow 2amp fuses quite easily. But before you fit a new one, pull the board out again and have a very careful look under a magnifying glass at your solder joints. Get a small stiff bristle brush and carefully brush across the joints in case there is a tiny ball of solder across two points. When you reassemble the unit, ensure that the ribbon connectors are central and fully pushed into the sockets. I'm sure you can recover your DMR E55 reasonably easily. Best wishes
