The alternator is situated inside the flywheel. This generates the current which is fed to the battery via the rectifier/regulator which is situated externaly on the low left as viewed facing the flywheel.

 

These engines do have a habit of losing the alternator magnets which come unbonded from the inside of the flywheel.

Sounds bad is it expensive job?

It's not hard to replace but I'd expect a new charge coil to cost upto £100 plus, just need to remove front cover maybe few other bits and unbolt it if its the charge coil that's gone get a tester and spin it over

Mine has the same problem. Have changed rectifier/regulater, still doing it. Battery/leads ok.

 

I just live with it and charge the battery about once a fortnight. Not really that much of a problem for me.

I had a problem with a kohler engine a few years back, thought it wasn't charging the battery but if fact it had cooked it. Put a new one on and it done the same and it turned out to be the voltage regulator.

Sounds like a plan dave!

 

Just bugged me! Ive whipped the covers off. What am i looking for? Magnet on flywheel ok. Cant see anything else... hmmm

You need to remove the flywheel as the magnets are inside. The magnet you are probably looking at is for the ignition coils etc.

It is i will access further this weekend. Any dodgy left hand threads...?

[Mark_Skyland]

Nope. Need to remove both coils then just one bolt holding it onto the crank.
