Voltage regulators all do the same job in name, but the one you need depends on whether you're chasing a charging fault on a Harley or powering a small circuit. This group covers both ends: three rectifier/regulators aimed at Harley Davidson Touring models and one ten-pack of 6V regulators for electronics. The price spread, from $10.99 to $79.23, is less important than making sure the component actually belongs in the system you're working on.
Quick take
- If your Harley is from the 1997-2001 Electra Glide/Road King/Road Glide generation, the $79.23 United States-made rectifier is the only one in the set that names that fitment.
- If your bike is a 2009-2015 Touring model, two options share the 74505-09/74505-09A part-number family: one at $54.00 with a more detailed spec list, one at $27.59 with a two-year warranty.
- If you're building or repairing electronics, the $10.99 pack of ten L7806 regulators gives you a fixed +6V, 1.5A rail.

Voltage Regulator Rectifier for Harley Davidson Electra Glide 1997-2001/Road Kin
This $79.23 regulator/rectifier targets the older Touring-family bikes: Electra Glide Standard, Classic, Ultra Classic, Road King Police, Road King, Road King Classic, Road Glide, and Road Glide variants. It's built in the United States and weighs about 2.37 pounds, with dimensions around 8.07 x 6.3 x 3.94 inches. If you're restoring or repairing one of these models, the obvious appeal is fitment coverage for that generation. The flip side is the price: at the top of this group, it costs more than either of the 2009-2015 alternatives. The listing also asks you to compare your faulty unit before ordering, so don't assume universal fit across all years.
74505-09 Voltage Regulator Rectifier for 2009-2015 Touring Models Electra Road S
At $54.00, this replacement is aimed at 2009-2015 Touring models, including Electra Glide, Road Glide, Road King, Street Glide, and Tri Glide according to the listing. It references OEM part numbers 74505-09A and 74505-09, and the spec list calls it a 2-volt, 38A, three-phase system. The aluminum body and 1.7-pound weight are described as supporting heat dissipation, and the package includes a UPC. If you want a direct aftermarket replacement with a clear part number, this is the middle-priced option. The limitation is year range: if your bike falls outside the 2009-2015 Touring group, this unit doesn't claim to cover it.
For Harley Touring 2009-2015 Voltage Regulator Rectifier 74505-09 74505-09A
The least expensive Harley option in this set is this $27.59 rectifier, which also lists fitment for 2009-2015 Touring models and carries the same interchange numbers, 74505-09 and 74505-09A. It's painted and made of metal, and the feature list calls it durable and easy to install. It also includes a two-year warranty in the listing details. The trade-off is that the title doesn't spell out specific model names like Electra Glide or Road King, so you need to confirm your exact Touring model before purchasing. For riders who already know their bike uses this part number, it's the lowest-priced way into this fitment family.
L7806 LM7806 7806 Voltage Regulator, +6V 1.5A, Pack 10
This is the odd one out in the group, and that's a good thing if you work on electronics. For $10.99 you get ten L7806 regulators, each delivering a fixed +6V output at up to 1.5A. It's a simple component for building or repairing power supplies on a board, not a motorcycle charging component. The price is the lowest here, but the real draw is the quantity: ten regulators on hand for bench projects. The limitation is compatibility: the listing recommends confirming compatibility with the seller before purchase, especially since the +6V rail and 1.5A current limit define exactly where it fits in a circuit.
