I was not sure of how many poles my alternator had so I picked a setting and tried it. On the third setting I got perfect results for my Yanmar diesel. 700 rpms at idle and 3000 rpms full throttle. Worth paying a bit more and getting something good! Review: Stopped working after only a few times but never on the road. I’m building an RV and bought this over a year ago and finally installed it a few months ago and it worked fine but this morning instead of 750 rpm’s it showed 5 rpm’s. Very unhappy. ## Features - Sierra 82302P 3 inch - Before ordering, please verify this is the correct part for your application.

I’m building an RV and bought this over a year ago and finally installed it a few months ago and it worked fine but this morning instead of 750 rpm’s it showed 5 rpm’s. Very unhappy. ### ⭐⭐⭐⭐⭐ Review *by T***L on 2 April 2020* Bought for an old Yanmar 3QM30. I installed a Balmar Alternator and including this Tachometer in the system was easy. Required slight modification of the instrument panel cutout, but otherwise one of the easiest jobs I've done on my boat. Love that I can now see my RPM! ## Frequently Bought Together - Sierra International 82302P 0-3500 RPM Dial Range Heavy Duty Diesel Alternator Electric Tachometer, 3" - Sierra International 80134P, Voltmeter, Heavy Duty Nylon, 2 inch, 12 Volt, 10 to 16 VDC --- ## 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.vu/products/612764963-sierra-international-82302p-0-3500-rpm-dial-range-heavy-duty](https://www.desertcart.vu/products/612764963-sierra-international-82302p-0-3500-rpm-dial-range-heavy-duty) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
