Starter Motor

As above....

What does the starter motor actually do please........

I assume ,with the power from the Battery, when you turn the key, it just turns the engine over ( cranks the engine ) nothing more ?

Anything else it does ?

Any information gratefully accepted as always.

The starter motor turns over the engine. creating piston compression & the compression.. accompanied with the prelim glo sticks in each cylinder starts diesel combustion. This starts the engine, a diesel engine doesn't us spark plugs.

Put your hand in front of a cold hair drier.. the compression warms up the air..and this heat & compression ignites the Diesel.

But you will need a good Battery...160 amps is needed to power this engine...over 10 times more than your house uses

So when I turn the key to re start a fully warmed up engine after I have turned it off to re fuel for example.

If it cranks a bit slower and continues to crank for 10 seconds , but won't fire up, is the starter motor at fault ?

Bareing in mind I have a brand new one fitted and also a new high amp top of the range Battery as well.

There's been much discussion on this forum about starter motors / batteries and difficult to hot start diesel engines. There was recently a starter motor fitted by a Toyota garage which turned out to be duff and there have been issues about bad electrical connections - particularly the main feed cable where it's connected to the starter motor.

Just realised it was you that had the issue with the replaced motor - sounds like the same problem again so another visit to the dealer sounds in order.

Well......

My Rav has gone back AGAIN as it played up about a two weeks ago now.

So I emailed my local Toyota's head of business AGAIN to complain,and........................

Have been given a 13 reg Aygo for a whole week FOC , until they fix my Rav FOC !

Ive told them it must start from hot in the same way it starts from cold......with no problem,each and every time,easily,quickly. and I wont accept anything less !

Had a phone call from them just before I finished work, they now think its NOT the 2nd starter motor at fault, but a loss of voltage to somewhere between the new Battery and the starter motor upon the hot start scenario.

See what they find.............................

Me thinks there is a lot a head scratching going on there :g:
