Starter motor issue

Afternoon folks, it's been a while since I've been here with a problem - two whole years without a hitch!

Starter motor started doing the thing where there is a click and then nothing, intermittently.  Assumed to be the solenoid on the way out, so this was the excuse I needed to replace the original Lucas lump with one of the hi-torque units (which incidentally are not quite a trouble-free fit - the terminals are on the bottom of the unit so your cables may not stretch).

All well for a couple of starts, but now doing it again.

I'm baffled as the click can only be the solenoid in the starter, and the trigger wire must be working.  I've tightened up the positive terminal on the battery on the basis that maybe it's not getting enough juice to fire the motor, but it still happens.

Any ideas?

cheers,

neil

    Don't discount the trigger wire etc, if that has a bad connection somewhere you might not get enough power to the starter solenoid to properly engage.

    First thing I'd check is engine earth, followed by battery condition then ignition switch.  Did you extend the cables during the fit?  If so, have a good look at those.

    The high torque starter I ordered arrived with the terminals in the wrong place. No way my leads would have fitted, and it should have been a direct replacement. Sent it back to PNM and they replaced it.

    I wonder if you have the same problem.

    I have made many mistakes in my life. Buying a multiple Lotus is not one of them.

    Thanks gents I'll get the emery cloth out.  Engine earths should be OK, I added another one as a precaution a while back.  Battery is a 3 year old Yuasa, spends a lot of time on a conditioner so I'd be pretty miffed if it's that but will check.  I had thought about ignition switch, hope not as I bet it's a real pain to replace!
