Re: Starter motor plastic cover removal

Dave, They are not directly connected. The R/W terminal energises the solenoid coil that moves the bar within that coil that then moves to create a link internally between the large terminal that has the big power cable from the battery to the starter motor internally & i think the W/LG terminal is ...

Re: Starter motor plastic cover removal

Dave, Thinking about it a bit more , the WR feed & terminal gives power to the coil of the solenoid & the W/LG terminal must be connected in parallel to the starter motor internal wiring that is made live when the solenoid bar is moved by the solenoid coil during cranking. (This applies to 1974 1/2 ...

Re: Starter motor plastic cover removal

Dave, I suspect it has to be on a different terminal to ensure it goes "dead" once the engine has started & cranking finished , otherwise you would get current passing back from the piggy back connection on the LT side of the coil where it meets the ballasted lead when the ignition is on & the engin...

Re: Starter motor plastic cover removal

Dave, The starter relay sends power to the solenoid which in turn moves to make the starter motor crank the engine via the WR wire. At the same time this should result in the terminal on the back of the solenoid to which the W/LG is connected being made live to feed the coil at 12 V. (Certainly high...

Re: Starter motor plastic cover removal

Dave, Apologies - i don't know why my last post was put up again! I recall the issue. With the boot removed have you tried connecting a test light or meter to the terminal on the solenoid that is energised when cranking(with the other lead to a suitable earth),having disconnected the existing non ba...

Re: Starter motor plastic cover removal

Well done Dave.
I have seen many MGBs where the boot is missing either through loss or owners finding it too much hassle to put back on & have seen the effects of muck & corrosion that Mike refers to, so worth making the effort to put back on!
Cheers,
Charles

Re: Starter motor plastic cover removal

Hi Dave, I've removed mine a couple of times over the years - it is certainly much easier when it has had some heat on it ,either a little while after a drive long enough to warm the engine up & the various components attached to it or the hair dryer ( or something similar) approach. I found the onl...

Hi Tim, I believe you have an early MGB Roadster - i.e. 1962 Per Barrie's Notes on the MGB:- G= MG H= Overhead valve engine N= Sports (2 seater) 3= 3rd series (the 1st & 2nd were the MGA L= Left hand drive (RHD cars have no letter) Per Clausager:- The engine numbers with that reference started with ...

Re: Bleeding the clutch

Not sure if you have also installed a new slave cylinder - if so , many of us found that to minimise packing the bleed screw comes in the wrong aperture so that the whole thing fits in a box.I realised this when i had it on the car & tried to bleed the system....
