Talk Morgan Forums Community Vehicle Talk (non-Morgan) Cable Tracker

Good afternoon Gent's Am I OK to use a Cable Tracker that has a Sender and Receiver 9 v both to check if I have a Short on my Morgan's Fuel Pump etc and has anyone any idea where the VCU would be on my 2001 Morgan 4 x 4

Kind regards

A multimeter and wiring diagram would be far more helpful Kevin. The latter are available for download here spilt into three parts.

Fuel pump issues are usually down to the relay, connectors or pump itself. There is also a safety inertia cutout switch killing the pump feed which can be triggered inadvertantly although maybe on later models.

Hi Richard, Thank you so much for taking the time to reply to my question,

And thank you for the schematics I will laminate them for use and safe keeping.

The issue I have has been going on for month's, I have changed all the relays, Fuses, and fitted a New Fuel Pump and fuel shut off switch.
I believe I have an electrical issue ( a short ) but finding a qualified vehicle election who is prepaid to come to my home in Southampton is almost impossible.

Fact is after I fitted the new pump everything worked well for about a month, then the pump would not pressurise the fuel system and the indicators stopped working, I know it sound nut's but that's what happened, Morgan have confirmed they would look at the car but it would cost some £1.000 there and back just to get the car to them, but as I live on a pension i though I would try to correct the fault before i take the nuclear option. anyway Thanks again, keep safe Kevin

Thinking of multimeters, does anyone know of a make that has long leads?

Would a nearer and cheaper option be somewhere like Berrybrook/New Elms/Williams?

Is this an intermittent fault, or is it now persistent (which would be much easier to debug). Are you sure there is 12V across the pump when the fault is present (which would suggest an earth problem somewhere i.e the currenty from the pump is not gettinhg back to the negative battery terminal)?

https://jvsautoelectrical.co.uk/ is a Southampton mobile electrician (but I have no experience if they are good or bad, or indeed mobile)

Is it perhaps worth reaching out to the local MSCC noggin and seeing if there is an electrical expert there? (https://www.logmog.co.uk/)

Sorry, can't be much help I'm afraid....

No need to buy a multimeter with long leads, just use whatever length of flex might come to hand, unless you are measuring critical resistance.

You may well measure full battery voltage across the pump supply and it`s ground with the pump unplugged, though that measurement is without the load of the pump in circuit, whereas while supplying the load that is the current draw of the pump, the voltage may fluctuate due to either a faulty connection on either the live or ground. In general ground connections seem to be those which cause the issues, that being the case, might be worth tracing to see where the ground makes it`s connection..?

Best of luck.

There are extension leads on Amazon. There are some specialist websites which sell that kind of thing too.

A pic of my meter`s extension lead, the Halfords price label denotes £2.29 so my guess is that I may have had it for quite a while, I suspect something similar may still be available and at less cost than a pucka set of leads...? Of course the crimped on male/female connector was an extra cost... (-:

Even more local to you (Southampton) might be SogMog, Colin Cruickshank is the Centre Secretary: sogmog.sec@morgansportscarclub.com

I carry a Halfords reel of wire in my car toolkit. Handy to extend/bypass etc. Also a cheap " multimeter" for basic emergency checks, test fuse, check voltage, current etc.
