The First Generation Ford Alternator, 1G Series Externally RegulatedIn 1973 Ford started using their first generation of alternators. Dubbed the 1G, this alternator was externally regulated in amperages ranging from 40-65 Amps. The 1G was used on the F-Series truck until about 1992. It was later replaced by the 2G series alternator from 1986 to 1992, the 2G is not upgradeable to a higher output because of it's weak bridge rectifier and the power plug can catch on fire from the higher amperage load.
The best high output upgrade for the early 1G series alternator and the 2G series alternator is theFord's Fatal Flaw with the Second Generation 2G Series AlternatorThe 2G series alternator, introduced to the F-150 Series of pickups in 1986, has largely been considered the bad apple of the bunch. Ford replaced the 1G's external regulator in favor of the compact internal regulator design. The flaw was in the power output plug and a weak bridge rectifier. The plastic power plugs, used blade type terminals which would loose connection and occasionally melt, short, and possibly cause under-hood fires. For this reason we recommend replacing the 2G series alternator with the later series with output battery studs instead of blade terminal plug.Replacing Early Series (1G & 2G) Ford Alternators with 3G self exciting or standard pig tail plug-in hook up.The, can come with a self-exciting voltage regulator which only requires the main battery wire to the back of the alternator. The only requires one ignition wire to activate the alternator and it can work with a no charge light (idiot light) which is the perfect unit to replace the earlier 1G and 2G series. Command window opens then disappears 10. The 3G has a heavy duty battery post, so the 2G series power plug issue is completely solved.

It also has a improved voltage regulator setup. The Third Generation of Ford Alternators, 3G SeriesAfter the successes of the externally regulated 1G series and the failures of the 2G series alternator, Ford Developed the. Introduced in 1992 to the F-150 line of Ford trucks, the had a heavy duty bridge rectifier with a sturdy battery post. The 3G voltage regulator uses the same 'D' shaped plug as the 2G, but it was further improved for the design. It has a stator signal connecting to the regulator, helpful in identifying the alternator.
All of these improvements have lead to Ford still using this alternator even up until the new '09 model Ford Vans which have some switched to a new Nippondenso alternator. Ford F-150 Splits Forks in Generation 10, 4G and 6G Series Alternators, The New Super-Duty LineIn 1997, Ford started using their new 4G series alternator.

In 1999 Ford actually stopped production of the F-Series F-250s and F-350s, naming them a whole new line of Super-Duty vehicles. All of the Super-Duty vehicles after 1999 with the Power Stroke Diesel now use our large case. The rest use either a standard, 4G, or alternator. Beginning with the 2009 models, Ford has gone with a new Nippondenso type alternator for everything but their diesel engine vehicles which can be ordered with dual small case alternators.
