Morris Minor Owners Club

It's been a while since I posted an update. I'm not sure the headlights are the direct fault now, as the alternator stopped charging with the headlights off when starting again shortly after a short drive. I think the headlights just make the problem more apparent or trigger it immediately due to th...

Disconnected the left headlight, started the car, jumped up to 14V turned the right headlight on with the switch, idled for 5 minutes and it stayed at 14.3V. Swapped the headlights over at the connector block, with the headlights off started the car and got a loud bang (sounded like a backfire) and ...

https://www.youtube.com/watch?v=IEylpJ8selc I recharged my battery and reinstalled it. In this video you can clearly see the problem. First I start the car with the headlights off and the voltage jumps straight up to 14.4V. Then I turn on the lights and it immediately drops down to 12V (not charging...

Yes that’s something to think about - the Chinese alternators would fail completely and never recover - this is the only alternator which recovers after a while. Of course I haven’t been able to test the alternator yet to see if it has recovered this time. Maybe the fan belt tension is too tight lik...

Thanks for your replies. KwikFit ran the car and measured battery voltage 14V, and then they put all the accessories on inc headlights and the battery was still charging at 14V so it passed that test. Then they put some gadget on the battery which gave them a reading of its health, can’t remember wh...

Hi all. I got my Morris Minor five years ago and have been daily driving it since (it’s my first car). I have done an alternator conversion due to how often I use the car, plus I have halogens fitted, a speaker, USB port. I’m writing this post from the hard shoulder on the M62, because once again I ...

Hi all. I've been to a car show today and got talking to another minor owner and he told me that all unleaded fuel at petrol stations is getting replaced with this new 'E10' fuel that is incompatible with vehicles before 2011. He said he'd been asking all the other classic car owners at the show and...

That's good news. My own Series II tank will soon be 65 years old. How well does the larger ESM fit? Presumably it doesn't eat into the spare wheel space? Mike Hi Mike. ESM sell both a 6.6gal low top tank and a 9.5 gal tank. I've fitted the 6.6 gallon tank which has a low top like the SII tank, so ...

Hi Ben Was this resolved? Hi everyone. Good News!!! :D I've just completed a 12 mile round trip, not long I know, but far further than my car used to go! Turns out the problem was either a blockage in the tank or fuel pipe, but I would think it's more likely that the tank was at fault. I've replace...

Even if it transpires the fault is not the pump, it's a good idea to keep one in the boot as a spare. I also keep a small square of fine Emery paper taped to the adjacent bulkhead, so that I can easily wipe the points in situ (dirty/pitted points being the most common cause when these pumps stop pu...

Hi everyone. Just posting an update on my car troubles. I can safely eliminate the fuel pump from the potential problems I hope. I've replaced my HARDI pump with a brand new SU standard type pump from ESM. I gave it a test drive on Tuesday and I'm afraid I managed 10 miles until tick, tick, tick, ti...

You probably should let the output discharge freely to complete the test. You must have had pressure in the hose to the carb and that stopped the pump. The pump runs until there is a 3psi or so pressure differential between inlet and outlet. Do it again with the discharge to an open container. The ...

Mine would be fine until it warmed up a bit. Probably the first thing to do is disconnect the inlet and plug it with your finger. If it ticks it is either the diaphragm or the valves leaking. The bubbles in the output also points to a leaking diaphragm. Although the fuel could be vaporizing in the ...

Hi, thanks for your reply. Do you know how I could test for a leaking diaphragm? I don’t have access to a replacement pump without buying one.

Hard to tell in the picture, but what I did what disconnect the fuel hose end from the carb and I put the end in a glass jar. As the fuel pumped and the end of the hose was fully submerged, lots of small air bubbles appeared. I suppose does this mean I have an air leak between the tank and the pump?...

Hi all. Just saw this and I wonder if an air leak sounds plausible? I will test soon and post my results.

The continued fast ticking of the fuel pump clearly indicates a fuel supply problem. What it is, exactly, needs to be ascertained and then remedied. No amount of other “remedial” work will actually make this fuel supply issue go away. The pump should only tick occasionally, once the carburettor is ...

Thanks for the help and advice everyone. I’ll inspect and clean the fuel pump filter and then swap the coil. If that doesn’t work maybe converting my distributor back to points will show if the electronic ignition is failing. Hopefully something out of that fixes the problem before I have to look at...
