Clansman 352 installation problem

Post by newtmo68 » Sat Dec 22, 2018 11:03 pm

Just finished installing all the PRC 352 radio equipment on my 1983 GS. When I turn on the 14v DCCU the green light default is flashing. It's getting 12 volts. Have checked all the ground/earth points. Other than the DCCU being defective what else could prevent the DCCU from charging the PRC 351 battery? Appreciate any suggestions.

The charge complete light on the later units will flash under the following conditions;
1. The DCCU is switched on and not connected to a battery
2. If the battery is faulty
3. If the charging lead is faulty
4. If the DCCU has a fault

That's it, nothing else, 2 and 3 being the most common issues.

Not any use to your question but I would like to fit this radio on my GS, But where do you wire up the charger too,as I have a connection lead but 1 end has been cut off. If somebody could post a picture that would be great,and sorry that this is not an answer to the original question.

Thanks Bob for the list. I have two Clansman 351 batteries and the green light flashes when I hooked up the DCCU to either battery. So using your list the problem is either the charging cable or the DCCU itself. I'm currently have a "used" charging cable so just ordered a "new" charging cable. Hopefully this will correct the problem before I have to order the more expensive option of another DCCU. Thanks again for your help.

As to ianmaden's question about where to wire the charger to I ran a 10 gauge wire from the positive post on the battery (or you can use the starter relay) to behind the driver's seat. There I mounted a remote fuse box (6 circuit). Ran the DCCU charger wiring to one of the fuse box circuits and used one more circuit for a map reading light. By connecting the DCCU charger this way I didn't have to worry about causing any problems with the old (1983) original wiring.

DCCU'S in GS vehicles are connected to the vehicle electrics via a one way power distribution box which itself is connected into the n/s rear rear light feed and earth wiring. This ensures a fused supply to the DCCU protecting it and the radio equipment and vice versa the vehicle charging system.
