I only hear of the LNs doing it but really any alternative that uses a similar regulator would do it as well. I put up with it during the cold months and forget about it during the warms months.

I have a procedure I can do to help curb or eliminate it during the cold months. I sometimes do it and sometimes I don't.

I would still recommend the LN at this point. As long as it holds up I don't see much reason to shy away from it because of the oscillation.

 

 

Once the cylinder has fired several times, it begins to generate it's own heat, really no need to run the glow plugs longer than needed once the cylinders are firing.

I'm sure Jack can tell you what happens to the tips of glow plows once they get to hot. I've been running a LN for 5 years and have a new spare LN in the box ready to go and the old stock unit that won't see the light of day, at least on my truck it won't. I don't have any issues with it cutting off early, cylinders don't start to misfire. I run a 1.0 cable from the right to left battery and a third battery to the starter only with a couple extra grounds. My plugs run the full time except summer and if they didn't, once the trucks running, it's running. It's not going to hurt it because the alternator cut them off early, they are still hot for a couple rounds, that's all it takes.

 

Another vote for L/N 230 have about 25K and 2 years on mine now no issues....

 

While Mechman may be located in Tennessee, and while Mechman may rebuild, and even build alternators from imported parts, I am doubtful that Mechman actually built the alternator shown in the photograph above.

To me, that looks like the alternator that Romaine Electric (in Washington state) developed for the aftermarket, using the alternator frame specs found in the 2008 Ford 6.4L, with Denso segmented conductor rotor/stator guts, along with an IDA regulator from the pre 1998 Fords, with a translator harness to bridge from D shell to our shell. The "development" work was in the 3 way port plastic SRE back cover that enables the same alternator to fit a variety of Ford applications. Romaine sells to rotating electrical shops like Mechman and DC Power, who in turn put their own labels on them and resell them as their own. That is likely one reason why DC Power started commissioning their own billet drive end housings, in order to differentiate their reselling of these Romaine alternators from everyone else's.

The CEO of Romaine Electric was also the president of the trade organization of the rotating electrical industry, which most aftermarket rebuilders and resellers participate in or interact with at some point or another. I'm pretty sure proper credit is first due to Ford Motor Company for commissioning the segmented conductor into a T mount frame in the first place, and then credit is due to Romaine for having the vision to develop it backwards to previous applications. All these other aftermarket alternator resellers beating their chest about them are simply reselling them, not building them, and likely taking credit not really due to their efforts. This can be true even if those companies do rebuild alternators as well as sell prebuilt alternators. And yes, I've seen the videos of Mechman's shop.

BTW, Denso Segmented Conductor (aka hairpin) alternators are great alternators, with far more efficient electrical windings that traditionally wound alternators.

 

 

Here is an older view on recommendations.

My uderstanding of one of the issues that DC power was having was the ability to keep
new build and repair parts in stock. So there was a chance you might get stuck somewhere
waiting on them to get parts .

Ed now has other brands that they carry.

I have a DB electrical 200 amp unit. Its over 4 years old now.

ENSURE you install a 4 gauge or larger wire from the alternator post to the passenger side battery or it WILL burn up. People ALWAYS forget or neglect to do this and burn them up.

 

Thanks for all the replys, I'm gonna go with the db, I really haven't had any issues with their products in the past, was putting them on a fleet of plow truck's we serviced and they worked great for them. And I certainly will be adding bigger wire.
