The original alternator was a “3 wire” alternator that used a purple and red wire along with the normal power and ground. This alternator just has a power and ground and self excites (no need for the purple and red wires). Simply tape off the purple and red wires on the engine harness and run this red to your battery, and add the ground. The factory sheet with actual test specs was a nice touch. It appears these are individually tested. My stock alternator was 65 amps at 6000 rpm (wide open) and this does 55 amps basically at idle, and 113 amps at 6000 rpm. Quite and upgrade. And simpler to install, arguably more reliable than the old “3 wire” gm alternator. Pros: affordable, excellent chrome work, great value and it puts out rated power and has factory test sheet! Mine has a set charge rate 14.2 volts per the sheet. Cons: none I have found yet. Review: Super sweet Chrome Alternator! DB electrical is the best .. - Last summer I bought an alternator from desertcart only for it to never work from day one. It took me a bit more time to get it installed on an rebuilt older skid steer I went through from the bottom up, long story short it never produced squat for output of 14+ volts! I even replaced the Voltage regulator and it still failed to work right. When I seen this Alt from DB electrical I jumped on it and when I installed it at first it didn't produce enough current output but after I increased my RPMs all was great again! 14.7 volts.. It looks fantastic but I didn't much care about how it looked as I needed to keep my battery charged! Thanks DB electrical, I've bought many alternators and starters and even a winch motor from them with any problems. If by the rare chance this alternator has issues I'll update my comment but my guess is DB will make it right as they always do, IMPO. Thx. ## Features - Spec: Unit Type: Alternator, Voltage: 12, Rotation: CW, Amperage: 105, Clock: 12, Pulley Class: V1, Regulator: IR, Fan Type: EF, Brief: MARINE APPLICATIONS, - Replaces OEM Numbers: ARROWHEAD: ADR0334-C, EMP PARTS: 4-6842, J & N: 400-12484, LESTER: 7152-105C, WAI: 7152CN-94A - 1-year warranty protects you after your purchase.

Upgraded the wire at the same time to 4 AWG - likely overkill, but wanted to since the new amperage from the alternator was 100 vs. stock 40-50. Works great and it's nice and shiny- Highly recommend to anyone needing to upgrade their older ski boat. ## Frequently Bought Together - DB Electrical 400-12484 Alternator Compatible with/Replacement for Marine Mercruiser 105 Amp Chrome Delco/ 10SI/ 1 Wire/V-Belt - Quicksilver 86166Q1 Bellows Adhesive – Resistant to Oil, Grease, Gasoline and Water – 1.5 oz Tube - New NGK Standard Spark Plug BPR6FS, 2623 Set of 4 Spark Plugs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/41090326-db-electrical-alternator-12-volt-replaces-arrowhead-adr0334-c](https://www.desertcart.us/products/41090326-db-electrical-alternator-12-volt-replaces-arrowhead-adr0334-c) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-02*
