The Dixson Inc Model 1501 076‑93176 is an analog tach‑dwell tester used to measure engine dwell time on 4‑ and 8‑cylinder vehicles. Common failures include loss of power or voltage drop across the internal regulator, drift or blanking of the needle display due to worn resistors or a cracked glass window, and poor clamp contact that causes intermittent readings. First‑check steps are: verify the unit’s battery or external power supply is within spec; inspect the clamp connections for corrosion or loose contacts; and compare the displayed dwell against a known good engine run to confirm accuracy.[oss-gpt-20b] |
