Hi All,
Long time reader, 1st time poster. I have 2 Volvo Penta AQ271A 5.7L motors in my Bayliner 2850. My boat currently uses the original Prestolite BID electronic ignition system and OEM Volvo coils. Both my Prestolite distributors are cactus. One the module is defunct and the other is advancing way too much. I have bought 2 new Mallory Unilite YLM624AV Marine distributors as replacements (they use a MUCH better system and are rock solid timing wise). They are fitted, timed and on the trailer the boat runs great. The installation instructions that came with the Mallory's says that I need to make sure that my boat is equipped with either loom resistance wire or ballast resistors. Failure to have either of these will cause the electronic module to fail, which obviously I don't want to happen.
I did check my voltage at the coil and it was 11V. My batteries were at 14.4V being absorb charged at the time (solar). I thought this indicated that I had resistance wire installed as I could not find a ballast resistor anywhere.
I am now concerned that this may not be the case and would like clarification of this if anyone here knows. So, my question is, do I need to fit ballast resistors to my system or does the original OEM system already have resistance installed??
Thank-you for any input.
Ian
