The 42MT starter has the solenoid built onto it like a pickup truck.
In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries. 8 amp draw doesn't sound like a whole lot to me, unless I'm not understanding something. It is a Delco 42MT, it is in a cummins ISX 15L, sitting in a heated shop about 60 degrees, the starter is drawing 1200 amps. The new PM 44MT has the same power as a 50MT with a little less current draw.

This design starter motor is ideal for On & Off road vehicles using large Diesel & gasoline engines. rent draw does not include the sole- noid, deduct from the ammeter read- ing the specified Current draw of the solenoid hold-in winding. approximately 150 amps : Valve spring pressure? Intake manifold vacuum: Idle: 16 in Hg 2,000 rpm under load: 14 in Hg : Exhaust system back pressure (measured after water injection point) Starter armature end play is the amount of horizontal or axial movement in the armature shaft after a starter is fully assembled. 1-page straight-driver starter like a 42MT with a gear-reduction starter? A: You can, but there are additional considerations to worry about.
SAFETY NOTE: Amp draw on a 12-volt circuit is cumulative.
Starter Drive Bendix Gear for The Delco Remy IMS Solution reduces amperage draw on the control circuit from 300 Amps to 4 Amps, ensuring optimal operation and reliability. 72 Highlights: Solid built 39MT Starter 12V 82 Degrees positioned Solenoid 100 % Brand New and made to meet the highest
A lot of times you can find a circuit where 12 volts are present but the circuit is not capable of carrying an amperage load.
If you take it to a shop they can attach a clamp meter and give you an exact number. You might say it is just a safety to insure the solenoid doesn't over draw the rated wire capacity of the start circuit The 42MT starter motor strap has had several different variations through its lifetime. Delco Remy 42MT™ Heavy Duty Straight Drive Starter. As this table shows, the need for excessive amounts of CCA to start the engine has changed due to advancements in vehicle technology such as gear reduction starter motors supported with low cut in alternators. 42mt starter amp draw Buy Rareelectrical NEW 12V STARTER MOTOR COMPATIBLE WITH PETERBILT 321: Starters - Amazon.
