Webb28 nov. 2024 · Calibration: First, you need to calibrate the constant current source by using a multimeter to estimate the constant current. Then adjust the value of RV1 till the point the current is 100 mA. Start by adjusting the RV1 to its minimum resistance to avoid any potential harmful current flow through Q1 and R3. Webb29 nov. 2024 · To check starter’s resistance connect black probe of multimeter to ground and red to positive terminal of starter. It should give near 4 to 6 ohms if starter solenoid is working well. If there is an open circuit, this could mean that either your wires are broken or shorted together somewhere in-between their connections to the starter solenoid. mcla math department
