Product Details

The Bosch 1986AE0143 is an electrical field regulator (also known as a voltage regulator or alternator regulator) designed to precisely control the excitation current supplied to an alternator's rotor field winding. By managing field current, this regulator maintains stable charging system output voltage across a wide range of engine speeds and electrical loads, protecting the vehicle's battery and onboard electronics from over- or under-voltage conditions.

Key Features:

  • OE-quality Bosch construction for reliable, long-service-life performance
  • Regulates alternator field current to maintain consistent charging voltage
  • Protects the battery and electrical system from voltage spikes and fluctuations
  • Direct-fit replacement designed to Bosch's original equipment specifications
  • Compact design for straightforward installation

Bosch is the world's largest original equipment supplier of alternators and charging system components, making the 1986AE0143 a trusted choice for restoring proper charging system function. Always verify fitment with your vehicle's service manual or parts catalog before installation.

The price was great and delivery out standing. Much greater than I ever expected. Great job.

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Great overall experience and fast shipping. Thank you.

part arrived on time and intact. Easy peasy.

The experience was good.

First time customer and very pleased with price and service.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Quick, Easy to use, great prices! Very excited to have found this!!

Great easy experience
