Starter Motor Current Draws

[Wilhelmus Schreurs]

Can anyone tell me, or lead me in the right direction as to where I could find the current draws for starter motors. I have a 3208 Cat and an 8V92 Detriot.

Thanks

Bill - Current draw will depend on temperature and the state of the engine
(compression). For my 3208, it always started easily when I had a single group
24 cranking battery that was rated at 800 CCA when new. I now use a single
group 31 which has a couple hundred more CCA.

Starter motors are a series wound
motor. The current draw varies with the motor speed and load. The
initial inrush when the starter first engages is quite high and then falls off
quickly as the diesel starts to turn over. Cold weather would make it
higher as the diesel is stiffer. A starter shop may be able to give you
an idea.

Bill,

It seems like I remember the Cat people telling me that I needed a battery with 1800 (or so) cranking amps.

Starter current is a tricky thing. An unloaded DC starter motor will not draw much current. Perhaps 100 amps for .2 seconds and then 10 amps to run. When the motor hits the flywheel teeth, depending on your batteries, cables, connection cleanliness, and starter condition, the inrush current will top 1000 amps for .2 seconds and then drop to between 400 and 900 amps. This is why jumper cables are a joke for starting unless they are 1/0 welding lead with parrot clamps and even then, it may not jump. DC motors are like goldfish. They will eat what they want, given their food supply. The 3208 will draw almost the same current as the 8V because of the 4 stroke condition. Either way, any good battery will load down to 10.2 volts while cranking and the currents are stout. Keep those connections clean and I replaced the stinky little #1 cable running to my starter with a 2/0. Every little .01 Ohms makes a difference.
