Starter draw in AMPs

Should be under 250 AMPS period. Anything over 200 is either bushings going bad or it is trying to compress water. Note: Gas engine.
Oil burners will always be a higher amp reading (50-60 amps) due to compression differences.

You can read the draw at either the starter or at the battery as the source is the battery at engine off/starter engaged.

All you need is have all of the ground wires leading from the battery terminal inside the amp gauge clamp. At the starter you need the LARGE wire inside the clamp and then set the meter to amps DC voltage. Pull the fuel pump relay and Crank for 15 secs and read the stored number. Highest is the number you need. SIMPLE.

NOTE: This test requires a fully charged battery battery to be an effective test.
