Has anyone had any experience with the DB alternators? I am looking for a higher output alternator for my 99 GL 1500 and this one is slightly cheaper than some others. Possibly easy to get rebuild parts for? I have redone many automotive alternators in the past. Just trying to do some research ahead of time as we are in the start of our 'cool' winters now. Looking to replace sometime before 1st part of March. I have installed heated grips that are really nice on cooler days and also
have a heated jacket liner that has not been used yet. Tried it out one day in my shop. Put it on and hooked it up, took about 3 minutes to warm up quite nicely. Can't wait to try it for real. I have been on the road out in the country as early as 1st week of March and most of the time April.

From what I recall reading about them, the internals are standard automotive parts, from GM vehicles.

So, a local repair shop should be able to fix it for you.
Also, it is easy for the DIY folks to service them also.

Most alternator failures are from carbon build up on the brushes, an easy fix.
Rarer is failed bearings, again, an easy fix.

The rubber drive bushings get hard over time, and cause noises... an easy fix.

Some after-market vendors use cheap wire and the insulation cumbles from the high heat that an alternator has to survive in.... it does not get any free air, all cooling has to be drawn in by the fins, and tucked in tight behind the plastics, makes that a tough job.

CompuFire builds uprated alternators...

Don't know about the alternators but I have installed 2 DB starters, 1 on my S10 and 1 on a friends 1 ton 454 truck, same starter. They have both been working flawlessly for about a year.

Likewise, don't know about the DB alternators, but I installed a DB starter on my John Deere lawnmower and two on my John Deere Gator. They were CONSIDERABLY cheaper than the OEM starters. The lawnmower is doing fine after a couple of years. The first one I put on the Gator broke after a couple of years. When I pulled it off, I discovered that a chunk of the housing had broken off and wedged in the flywheel. I complained to DB that it looked like a manufacturing defect and even sent pictures, but they just shrugged it off since it was out of warranty. I did install another DB in its place, but suspect that I'm getting what I paid for.

Limpy, We installed a DB alternator on my friends 1997 Gold Wing SE last year. It performs quite well.

Jus an FYI......

The "exciter wire" on the DB is hard wired to the alternator (not a plug in) as on the OEM alternator.

That "Exciter wire" plugs into a connector behind the left inner fairing panel (behind the reverse lever).

You either remove the left inner fairing panel (to make the connection) or do some cut and splicing of that "exciter wire"

Your choice......!!..

I replaced mine with one from LACtrical. Lasted 7 months. They sent a new one, lasted 3 months. Then they quit responding to me. I bought one from DB, been going strong for 4 years.

Do you mean I can 'cut & splice' the existing wire on the bike to the alternator? That would be quite easy to do I would think. I sure hope so, I plan on ordering it about the end of Feb. so I can get the most use out of the warranty in case it goes out during our rather short riding season here in ND.

I know, they are expensive.
When I bought the trike ('97 GL1500) from a doting owner whom maintained it, whom owned it from infancy when it was coming out the crate as a 2 wheeler, whom converted it to a three wheeler, among extras on it was a Comp-u-Fire alternator. I had a failure in 2005 one cold rainy day while on a group ride. Short of it, buddy had a spare I put in to finish the trip. Got home, took CuF to local elec motor / alternator / generator shop. Was a single open winding in rotor windings, likely a solder joint he said. He recognized the innards, was a Delco-Remy (Delphi) CS121 with a different end frame and drive vane setup to mate with GL1500. $104 later, I had a new rotor, brushes too. Put it back in, working ever since. I looked on Ebay once in about 2012 or 2014, just playing, found a low miles CuF off wreck up for bid, bids were really low, so I bid little higher max and figured someone would snag it up, I won it for about $120 with shipping. It was a higher serial number, looked new too. It was put in as a test, I left it in and put my recently fixed one away as spare.

CuF is a CS121 Delco Remey or Delphi Alternator. 1999 Saturn. Any rebuild parts kits for a CS121 or CS130 will fit. Uses large Honda OEM O-ring at install face, uses a National 471224 or Chicago Rawhide 9678 shaft seal. Temperature compensating internal regulator that cuts back charge rate when it warms up like after battery is recharged.

Once started, the trike idles at over 14 vdc but when warmed up, more like 13.6 vdc. I use a Odyssey PC680 AGM battery like the first one that I put in in 2004 and which … lasts still in my old '85 that I sold, I put a new one in the trike in 2016. I found one hiding on a bench behind stuff that I had bought for the '85 but never put in so I put it in the trunk (more useful there than at home when or if ever needed I think) .

It's bigger, I do have a OEM with 9,xxx miles on rebuild given me that stays in the trailer now as emergency back up. The extra lug you see is just along for the ride.
