problems with club voltage stabilizer

[SprintMWU773V]

Have had the club spec voltage stabiliser in the car since August and when I went to get my MOT I noticed that I was showing over 1/2 a tank of fuel when I knew I didn't have even 1/4! After I passed the MOT (1st time of course) I checked my earth on the VS and noticed that one connecter may have been slightly loose. It's happened before causing much the same problem. I renewed my earth cable only this time soldered the connecters on. I've screwed the earth into the bulkhead and has always been fine there. Checked with the ignition on but not running and it's showing 12v and when running a shade under 14v. <br>
<br>
Either my earth is not good or there is a problem with the unit? For all of you using the new VS where have you earthed it? Are you relying on the screws or are you using a separate earth lead? Also is there another way to test the unit say by putting my positive lead on "I" and finding a suitable earth with the negative end? I'm afraid I'm not very good with electrics.<br>
<br>
Any advice gratefully received as ever!<br>

Possibly a fault on the fuel sensor?<br>
<br>
By the way I have an Inca sprint MWU758V, we are very close on registration.

I'd heard from mem sec that there was a very close registration joining the club. Hope you have better luck trying to get a heritage certificate (if you want one) than I did!<br>
<br>
Have ruled out the tank sender as the temp gauge is giing silly readings as well.

I've sent off for a new one from the club, sent my old one but as yet had nothing back. I must try and ring up the club and see where its got to.<br>
<br>
My fuel guage & temp read too high, hence need new one

I'm using a club VS, but before i fitted it i cleaned up the corrosion from the screws, and also removed a square of paint (about 10mmx10mm) from behind the inboard screw, then sprayed Clear Protective Lacquer on it to stop further corrosion.<br>
Not had any problems with it, although I would be interested to see if running another earth from the body of the VS to the car (just slap it onto the main battery earth for testing purposes) would cure your problem.

Loads of them in use now and no faults so far, but there can always be a first. Identify the 'feed' to the VS, this should read the same as battery voltage. The Output should be 10V +/- a natts knacker. the uprated VS can be tested with a digital voltmeter, the std VS need a good quality annalogue meeter to test.<br>
<br>
Daily Sprinter, I have found your cheque and order, my fault, i'd opened the Jiffy bag, chucked you old VS in the box of old units and moved on,Jiffy bag was in the box of old jiffy backs ready to be recycled <!--EZCODE EMOTICON START :o --><img src=http://www.ezboard.com/intl/aenglish/im ... rassed.gif ALT=":o"><!--EZCODE EMOTICON END--> .

As much my fault as yours, I did not want to draw attention that there was a cheque in envelope on the jiffy bag.<br>
Never mind my restoration is taking now forever, the paint sprayers need a kick up their arse. I'm going to DA the car in their workshop as they complain so much about a bit of rust, I think they would like me to spray it aswell

I figure it's hard to earth straight into metal unless it's really clean so will try a few other things then hope for the best. I've no reason to suggest the unit is faulty most probably my incompetence! <br>
<br>
Glad they are selling well it's made a real difference to my car not least cos I can trust the fuel gauge and not run out of fuel like last summer!<br>
<br>
Hope Gaydon goes well, not sure if i'll be coming as my Dad wants to install his Midegt engine into the new shell and if i'm not there he'll never get round to it. <br>

Mark, got your message, will call tom evening. 'Earth Wire' confuses me a tad <!--EZCODE EMOTICON START : --><img src=http://www.ezboard.com/intl/aenglish/im ... ohwell.gif ALT=":"><!--EZCODE EMOTICON END--> . The units are normally earthed though their case (standard and uprated) there are only two wires to the unit, one a feed and one the output. Units have four terminals but only two terminals are used. There should be no other feed taken off the VS other than to the gauges ( it has been known for feeds for other things to be taken from the VS which results in the VS getting fried <!--EZCODE EMOTICON START :rolleyes --><img src=http://www.ezboard.com/intl/aenglish/im ... s/eyes.gif ALT=":rolleyes"><!--EZCODE EMOTICON END--> )

uhm, yeh, agreed about the no other wires apart from instruments....but....the electronic ignition i have on mine has an input from the VS. I didnt fit it, but im assuming this is correct? <br>
<br>
Dark green input, light green output (to the instruments), plus a feed from the input side going to the Newtronic leccy ignition.<br>
<br>
Had a hunt around, and can't find the wiring diagram for the leccy ignition. If this is meant to be unrectified, maybe it could go on a better feed?

<br>
The feed for my Newtronic ignition unit just comes from the coil positive. It's always been like that and it's run for a couple of years (20000 miles) without any problems.<br>
<br>
I think the voltage stabiliser gives a steady 10V for the fuel and temp gauges from a fluctuating (11-15V) DC input. The output from the alternator is already rectified, otherwise the battery would never charge!<br>

I might have a play around over the weekend. I'm tempted to go out now, but I'm going to warwick this afternoon, and yoiu all know what will happen if i lift the bonnet just before i'm meant to go somewhere....<!--EZCODE EMOTICON START :o --><img src=http://www.ezboard.com/intl/aenglish/im ... rassed.gif ALT=":o"><!--EZCODE EMOTICON END-->

Having carried out some more tests the unit is clearly earthed properly with nothing else attached to it, i.e. earthing using the screws into the body. The flying earth lead I fitted didn't seem to help! I haven't attached anything else to it to feed any other supplies (nothing else to supply). <br>

Can't for the life of me understand why someone would want to take a feed from the VS for an Eleccy Ignition, Wots wrong with the fuse box or as Dave says, the feed to the coil <!--EZCODE EMOTICON START : --><img src=http://www.ezboard.com/intl/aenglish/im ... ohwell.gif ALT=":"><!--EZCODE EMOTICON END--> . I would have though that the Ellecy Igntion would require a 12v feed. Now i'm no Electrical Guru, but the VS are designed to serve instruments which will have a certain 'draw' (AMPS IIRC). Start increasing that draw and one could overload the VS. The only uprated one that has gone faulty so far was indeed used to supply a feed to the elctronic ignition which 'fried' the VS. I'm sure our remanufacturer will (out of curriosity, no warranty implications cos of cause of failure) have a gander as pass verdict <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/intl/aenglish/im ... s/wink.gif ALT=";)"><!--EZCODE EMOTICON END--> I've checked XAA 2x Dark Green to Terminal B and 1 x Light Green to Terminal I. I've not put voltmeter on but B = Battery & I = Instruments ???

Indeed "B" is battery and "I" instruments, according to my little leaflet that came with it you measure voltage between "I" and earth e.g. the case, I'm getting 13.8 volts which is somewhat above the ideal of 10v.
