Complete EMPI 12V 55-amp alternator conversion kit — black finish, internal voltage regulator, all-new components. Everything you need to replace a tired factory VW generator with a modern alternator on Type 1 air-cooled engines. EMPI part #00-9486-0. The standard upgrade for any 12V Beetle, Karmann Ghia, Type 3, or Bus running modern accessories.

Why a complete conversion kit (not just the alternator)

Going from generator to alternator on an air-cooled VW isn't just a part swap. The alternator mounts differently than the generator and requires a conversion bracket to bolt up correctly. The complete kit gives you the alternator plus the bracket and any other adapter hardware needed for direct installation — no chasing down parts mid-install.

The internal voltage regulator eliminates the external regulator box on the firewall, simplifying wiring and removing a common failure point. EMPI builds these with all-new components rather than rebuilt cores, which matters significantly — rebuilt alternators are a frequent source of premature failure in the air-cooled VW world.

Specifications

  • Voltage: 12 volts
  • Output: 55 amps
  • Regulator: Internal
  • Finish: Black
  • Kit contents: Alternator + conversion bracket + mounting hardware
  • Construction: All-new components, not rebuilt
  • Part number: 00-9486-0 (EMPI), also stocked under Washburn's #E41

Fitment

  • VW Type 1 air-cooled engines (Beetle, Karmann Ghia, Type 3, Thing)
  • VW Type 2 Bus through 1971 (Type 1 engine)
  • Cars converted from 6V to 12V

Will NOT fit: Stock 6V applications without converting the entire electrical system. Will not fit Type 4 engines (different mounting geometry — 1972+ Bus, 411, 412, Porsche 914 use a different conversion).

FAQ

What's the difference between this kit and #00-9486-7?
#00-9486-7 is the alternator only. This kit (#00-9486-0) includes the conversion bracket and hardware you need to bolt it to your engine. If your existing engine already has the alternator-style bracket installed, you can save by buying the alternator only. If you're converting from generator for the first time, get the complete kit.

How long does the install take?
For someone comfortable with basic auto electrical: 1–2 hours. Remove the generator and its wiring, install the bracket, mount the alternator, connect the wiring, run the fan belt. Test the charging system before driving.

Do I need to remove the old voltage regulator?
Yes. The external regulator on the firewall is no longer needed — the alternator regulates internally. Disconnect and remove or bypass it.

Will my factory ammeter still work?
With proper wiring, yes. The alternator output can route through the original ammeter circuit. Some installations route the high-amperage charging line directly to the battery and use a voltmeter instead — your choice based on your specific gauges.

What size fan belt do I need?
The fan belt size depends on the specific alternator pulley diameter and your fan pulley. Most installations use the standard VW air-cooled fan belt; some performance pulley combinations require a slightly different size. Check the belt fit after installation.

Will this charge a discharged battery faster than my generator?
Yes, significantly. Generators produce very little charge at idle and only modest charge at cruise. Alternators produce useful current at idle and full output at moderate RPMs.

Tough little toy for super chewers.
Size: Shoes
Great my two Yorkies. Bought two. So far, still in one piece. UPDATE: This toy does not stand up to being washed. Since it is a "material" and not rubber, I would advise against buying it if you wash your dog toys. Sorry I bought several.

Not a durable toy.
Size: Drop Ball, Size: Drop Ball
I was very disappointed in this rope toys. It took one day for my Border Collie to destroy it. The rope is not a durable material at all. I had a rope toy that was like this one several years ago, but it was much more durable. It lasted a couple of years. I think this one would be great for a small puppy, but not for an adult dog. Very disappointing!

Fabulous play!
Size: Drop Ball
It is small for my 1 yr old girl boxer... my bad for not reading the product size details. The tug rope is great, but my rough boxer loved it too much and couldn't be trusted with it after much play. This toy opened the door for my purchasing tougher rope pull toys from the same brand.
