Recommendations For Altronic CD-200 Installation To Prevent RFI (Radio Frequency Interruption) & "Ghost Shutdowns"TRANSCRIPT
` May 7, 2007 Wiring Recommendations
All ground wire connection points should be free of paint and other contaminants. Cleaning of these surfaces should be implemented as a routine maintenance procedure.
A 10 gauge ground wire should be installed from the common coil ground point on the
coil bracket direct to the engine block. The attachment point to the engine block should not be shared by any other grounds.
Continue the use of a large ground wire from the engine block to the panel stand.
Add a 10 gauge ground wire from under one foot pad of the CD200 to the above ground
point in the panel stand.
Add a 10 gauge ground wire from one of the foot pads of the CD200 case to the battery negative.
Ensure that there is at least a 10 gauge wire that connects from the battery negative
directly to the engine block.
The ignition F-lead (shutdown lead) should not run in the same conduit or share a panel penetration point with any dc power or low voltage signal (magnetic pickup, transducers, thermocouples etc.
The ignition primary wires should not share any conduit or panel penetration point with dc
power supply (battery or alternator) or any other low voltage signal.
Ensure that each secondary lead makes a secure connection with the spark plug terminal and the other end is fully seated in the coil high voltage cup. Failure to do so can result in auxiliary secondary gaps that can result in high levels of RFI that can adversely affect the performance of the CD200 ignition and other electronics.
Always ensure that resistor spark plugs are used in new production and all field
replacements. Non resistor plugs can result high levels of RFI that will adversely affect the performance of the CD200.
The spark plug gap on new plugs should not exceed .020,” or the smallest gap that
results in reliable operation.
The “+” 24VDC power should come from the battery positive post, and should be fused. Do not originate the CD200 power from the alternator positive lug, or an electric starter positive lug. These are both noisy sources which can damage the CD200 and/or cause erratic operation.
