Sierra 57901P Voltmeter Amega 8 18 Review

This voltmeter is a great addition to any automotive interior. The design is sleek and modern, complementing any dashboard. The readings are accurate and easy to read. The only downside is that installation can be a bit difficult for those who aren't familiar with electrical wiring. Overall, this product offers both style and function and is a must-have for any car enthusiast.

Ideal for all new sensors. I have replaced all my old gauges with these, speedometer, water pressure, temp and fuel. You look absolutely amazing. The first thing to do before installation is to replace the light bulbs. Replace them with Red Bright Star LEDs (also from Revain). (Red does not affect night vision) It really complements the look of the sensors. Great gauge set.

My boat has an unregulated engine power (81 Johnson 50 hp). So I'm not only worried about the battery draining, I'm also worried about charging it. Since my fish finder has a digital voltage readout, this sensor is really just a backup in case my fish finder fails. I chose it because all my other gauges are also the same style as the Sierra and I love the look of these gauges and they work great too. Never had any fogging or water ingress issues. I would like this sensor to have a larger span…
