There are 87 Newell's without the ddec and I don't personally know of any others that do have it. From what i understand there was no ddec in Newell's prior to 87. Brads is an 88 (or maybe an 89) and it has ddec2 which has the breakers for the ddec2 in the electrical compartment beside the radiator. Any way, if anyone suspect they may have this same problem the ddec is connected to the engine batteries with its own 12 gauge red and black wires. This is so that the ddec is not disconnected when the batteries are turned off. These wires are fused with 15 amp fuses housed in rubber fuse holders on the front wall of the passenger side of the engine compartment. Hopefully there will be pictures here to show the location and identify the fuses.
The symptoms of the problem are: complete loss of power, virtually no response to throttle under load and no lift on the pressure needle. The side of the motor that is still running is hot and the other side is cold to touch. Each side of the engine has its own ddec fuse. Maybe this will help someone else. It is really disturbing to have your 8V92 act this way when you don't know what's going on.
