Thread: 24v compact starters

$US296 plus freight from Bosch Alternators | Starter Motor | Delco Remy | Elreg Distributors LTD in Canada.

Today I decided to give it another try and it started. I'm still ordering a new one, but this means my garage isn't blocked by 2.3 ton of rover while I wait for it to arrive.

New starter is fitted.

The starter which arrived from Elreg in Canada wasn't branded and had "brazil" as one of the only real markings on it. Same package as my existing starter and it comes with a full dyno test-sheet and graphs of speeds vs torque and current etc.

Highlights of the dyno sheet:
4.44kw max power.
7648rpm free running.
763A max current
40.6Nm max torque

To fit it I unbolted and threw away the "safety relay". It appears most new starters come with these and I have no idea why.
I also unscrewed the solenoid and rotated it 120deg (it has 3 screws) to put the hot-wire and signal wire clear of the chassis rail.

The old starter had been continuing to play games, yesterday morning it wouldn't crank fast enough to start. Every day or so an attempted start would get a "click" and no cranking.

The new starter is an animal, my tacho isn't accurate enough to tell the exact cranking speed, but it feels like 500-600rpm. It seriously cranks just below idle speed (it was 1 deg C when it was fitted) and sounds like an air-drill. I measured the max current draw and hit 300A, compared to 520A on the old starter. It now starts so fast now that average cranking amps can't be easily measured.

The before/after change is that big I find myself laughing after turning the key. The starting of this has always been marginal and required batteries in excellent shape. Now it's awesome.
