2016年1月22日 · When I check Deere's ordering system, the Ar65444 shows subbing to AT149002. That number is still available from Deere. Pricey at $143.70. The sending unit is tested with an ohmmeter. Tank empty should be 0 ohms, half full 15 ohm, and full should be 30 ohms.

2021年6月10日 · What P/N are the gauges? The 0-180 OHM gauge P/N is AL24187 subs to AL24294 There are gauges that are 0-30 OHM (30 OHM = Full) , P/N AT20175, AR65444, AT149002, these would read full all the time with a 0-180 OHM sender.
