Real-World Testing: Putting Sierra International 185711 185711 Voltage Regulator to the Test
First Use Experience
I tested the Sierra International 185711 directly on my 1968 Chris-Craft Commander during a shakedown cruise on Lake Michigan. The installation was straightforward, thanks to the clear markings and a wiring diagram I found online. After connecting the wires, I fired up the engine and immediately noticed the charging voltage was stable at 14.2V.
The weather was a mixed bag during the test – sunshine, followed by a brief but heavy rain shower. The Sierra International 185711 continued to perform flawlessly, maintaining a consistent voltage despite the changing conditions. I didn’t have to make any adjustments once the regulator was installed.
The installation was fairly easy, but matching the correct wire gauge to the terminals was a little finicky, as they are designed for the original wiring harness of older engines. A little dielectric grease on the terminals helped ensure a good connection and prevent corrosion. No instructions were included, but the installation was simple enough for someone with basic electrical knowledge.
Initially, I was concerned the regulator might not handle the fluctuating loads of my older generator, but it proved surprisingly robust. It handled the load flawlessly with no issues at all.
Extended Use & Reliability
After a full boating season, the Sierra International 185711 has proven to be a reliable component. I’ve put over 100 hours on the engine since installing it, and the charging system has been rock solid. No more flickering lights or worrying about a dead battery!
There are no signs of wear and tear on the Sierra International 185711, despite the exposure to the harsh marine environment. The terminals are still clean and corrosion-free thanks to the dielectric grease. The unit itself still looks brand new and I have not observed any signs of corrosion whatsoever.
Maintaining the Sierra International 185711 is pretty simple. I just periodically inspect the terminals for corrosion and apply a fresh coat of dielectric grease as needed. This simple preventative maintenance should keep it running smoothly for years to come.
In the past, I’ve had voltage regulators fail after only a few months. The Sierra International 185711 has significantly outperformed my expectations, providing stable and reliable charging throughout the entire boating season. It’s a testament to the quality of Sierra International‘s parts.
