DC power alternator

Ok so my truck 2006 Harley model only has 1 alternator. On long trips etc voltage always settled in at 13-13.4. Had my ficm fixed and decided to order a dc power oem 185 after talking to Ed a ficm repair. Well this weekend while waiting for alt, the truck voltage when started after glows voltage only came up to 12.6 twice while do errands. Parked truck knew I had an issue didn't wanna smoke ficm. Today I installed the dc power. Had my batts unplugged since yesterday waiting for new alt took old one out. Before hooking up batts I checked with a meter, 12.9 on both. And they passed a load yet while ficm was out. Got alt all bolted in started truck and immediate difference.
Well I have been having blue smoke issues for about a month now since atlas 40. Got worse past week. Would smoke out a bunch at idle take off and sometimes at idle period. Also tranny started shifting funny hanging up shifting outta third sometimes softer shifts all around. Well got truck warmed up took for a couple mile ride and smoke is damn near gone. Jut the usual (as I'm told) puff at take off 90% less than before used to be a mini cloud. Tranny shifted firm and smooth again like it used to. So long story short even though my numbers on cts always were within parameters the truck was telling me something wasn't right. I know now cause alt did take a dump anyway, only at idle higher rims would be 13.6 to 13.8. So to all the fellas with smoke tranny problems triple check power station first. I will be going to work soon and whi,e monitor next couple days to see if it stays status quo or I have a real problem. Thanks for your time josh

Thats good to know. Just to see where mine stood last year, even with no signs of trouble, I had mine tested, and it tested bad. So I agree, no bells and whistles does not mean that you don't have a problem. Are you going to do the Wiring mod that Ed recommends? Meaning, installing a wire directly from the alternator output to the battery. I have a stock alternator so I was going to put in a 4 ga wire with 125 amp fuse. With out looking at a table, you would have to go larger. Any known pros/cons?

No wiring mod i dont pull much more current than stock other than a trailer and plug in cooler. Drive to work lots less smoke. Small puffs only from dead stop. Little black little blue sometimes. No smoke that i saw at idle. Burried pedal to floor on high shifts great. The response with the truck just plan feels different. Much more responsive
