MGTF160 2004 - Central Locking/Alarm Issues

You can buy off eBay small volt meters, these are inexpensive, a couple or three quid is all.
They are an inch x three eighths at a guess, I’m not at home at the moment to measure, but that will convey their size.
A little bit of ingenuity will find a place to fit one & these can give you a view of not only the battery condition but indicate other electrical niggles.
These come in two & three wire types; the two wire is self explanatory, in the three there is a constant feed with the meter feed on the third. These are for instances where there is a difference in the maintained voltage & the measured voltage.
You will also find on the universal everything superstore called eBay metres that measure voltage & current, the current being measured across a shunt.
Walk straight past these & look at something else, these are great in power supplies, I use several, but for cars they can be a pain in every part.
I’ll post some pictures later when I’m back in the workshop

As promised two are on the car the other is an odd USB voltage tester. The six & a bit voltage is across a variable power supply on the blower motor.
The third is across a fag lighter socket. I dispensed with the socket in the car but still require one for the kit to re- inflate a tyre after a possible puncture.
My main volt meter is in a combined instrument cluster in the space vacated by the fag lighter.
You probably didn’t want to know all that!

Why am I such a failure with pictures? Sometimes it works with not a problem, then the system rejects me for a bit & I’ve to repeat. I do the same each time & with a failure rate of 50% plus.

Hi Fellow MG TF Owners

We finally gave in and took it to the Specialist

They plugged it into the analyser, and it said that the alarm has been triggered 4 times by the Front Door Latch Assembly.

There appear to be no new parts available, so we had a second hand part fitted.

It seems to have fixed the problem

We now have a 'winding sound' when we use the remote that we had never noticed before.

For Info the part number is

FQJ102262PMA - Front Door Latch Assembly, RH, RHD for Key and Remote

Rimmer Bros .. no longer available

I got them to give me the old part back, you never know I might be able to fix it someday? I never throw out car parts for old cars now.

Thanks for listening
Tim
