My S1 starter motor doesn't always turn. I get a click, the immobiliser light is off & when I rock the car in gear it will release & start.

I plan therefore to replace the starter motor.
Has anyone done that ? Any advice on how to do it & who to get a new one from?
John

I wonder if the "Hi-Torque" type starter is available to fit these engines. Probably not necessary, just thinking out loud... smile

I had problems with my 4/4 1905cc sometimes it would start sometimes it refused this was anyday and any weather. A starting motor with attitude . Ben Duncan had sent me several one may start it when cold but not hot . Then another would do the other way . It was like banging my head against the brick wall . Lying in the snow is no fun . So I contacted this firm and asked if they could help they made me one and never had a problem its a few years ago one chap on TM had the same problem and I gave him the firms details he popped it on TM they sorted his problem also . May be worth a telephone call.

John, never known an S1 Roadster starter to fail, are you really high mileage with 1000's of starts ?

First I would clean up the main heavy cable connection into the solenoid & engine earth strap, they often look a bit crusty on Mogs I've worked on

Check the hole at six o'clock in the bellhousing John. You can see the ring gear, and if a cover plate isn't fitted it will allow water and road debris to enter the bellhousing.

The starter on my Roadster had a Jaguar sticker and number.....if you look at my early posts there's photo which shows the number.

Dave,
I covered the bolt hole a long time ago.
In Holland this week but will check the car Friday.
John

Also plan to check all the connections & replace the relay.
The car has done 35.5k miles.

Just a thought but starter solenoid which piggybacks the motor may be at fault. Symptons are loud click but no churning of engine.

Mechanics stick a large screwdriver across main solenoid terminals and see if motor spins up. It won't engage of course but indicates which is faulty. Not sure if latest starter motors have service replacement solenoids though.

Definitely check the solenoid and connections, especially the earth.Years ago I had a car (not Morgan) with the same symptoms of clicking but no engagement. The motor itself was ok but the solenoid failed to engage the gear. A local auto electrical specialist cleaned and sorted it. I occasionally had to tap the solenoid (with a piece of wood )on the top of the motor to unstick it.

Could be damage to the ring gear or starter dog.

Yes to work efficiently the solenoid armature has to be a close fit to the soft iron core surrounding it, which provides the magnetic field to energise. A tiny amount of corrosion on the armature can cause it to partially jam giving rise to the temporary cure of tapping it with a soft hammer.

The most unusual problem I had with a clicking solenoid was a hairline crack in the battery positive terminal.

If it's the Jag one fitted to mine then it already is a high torque type, the problem with mine was that it was over greased and the dust from the clutch gummed up the works in the solenoid.

Stripped it down cleaned it leaving the shaft grease free, put it back on and it worked a treat.

I had a similar problem on a K series caterham, that didn't like to start when the engine was hot. Being a passenger on a track day with my son facing oncoming traffic at Brands following a spin, reminds you why you need a reliable starter!

It was finally tracked down to the starter not being exactly square to the flywheel and ring gear this was exaggerated when hot, effectively jamming the starter. Being tucked up under the exhaust manifold, didn't help either. A high torque replacement and some fettling of the mounting flange to square it up, solved the problem.

Not spinning also helps blush

Well as I had time today & it is a balmy 10c so I started the testing.
To my joy when I used a jump lead as a second earth it started. Take of the jump lead a it would only click.

The earth from the engine is hard to reach. I had to take off the air filter for access.

I cleaned up the contact areas & rebuilt it.
Will now buy a second earth lead as belt and braces.

Yes Richard. I spent last week on holiday worrying about it.
The crazy part is the earth looked fine & was tight.

Good result John. As the chassis is an important part of this high current circuit it may be worth checking the negative battery connection to it as well.

Ohms law dictates that a fixed resistance will create a volt drop proportional to current.

Similar problem with my first 4/4. Starter always turned, but on a cold start after a few days non-use would always be slow.
I ended up adding an additional earth lead from gearbox to chassis and replacing the battery lead.
