Electrical gremlins

[steve j]

Oh the joys of S ownership My S has thrown a couple of electrical gremlins at me. Fan stopped working, but works on the overide switch, the radio is dead, fuze ok and power from the ignition. Today I put a new battery on and it won`t even turn over . Out came the trusty volt meter and I have power all the way to the ignition and to the start button, and have power to the solenoid cable, looks like the solenoid needs looking at. The annoying thing is I`ve just put the body back on. The volts gauge is reading only about 11 volts despite a new battery giving over 12. I`m itching to get it all sorted and get the old girl out again .

Have you checked all the earths are good?

Have you checked the otter switch?

It`s a new otter switch, but I`ll check it with the volt meter, the car was running a few weeks ago on the key and button, no harm in checking the earth.

Steve,

Just the voltage thing would point to earths or a a "dry joint" in one of the major connectors. If I was you I'd take the earths off clean to barite metal and put back on with Vaseline covering, then split all the big connectors clean with contact cleaner and reconnect. When doing earths also do the starter motor.

Btw any sign of the cutter at work being back on line to do my gear stick surround?

Hope above helps and it runs fine afterwards

Eta if the earth wire from the battery (or any other one)is breaking down you may not see it and it can give temperamental and intermittent symptoms so jumping each out in turn may work if the former stuff doesn't. Note this will probably not show up on a DVM either

Guess I`m going to be busy down at the starter, the cutter at work also has electrical gremlins, I`ll get out the air tools mark

Don't worry about air tools mate I am happy to wait just you'd been quiet for a while so thought you'd become ...........chimerified.....😱😱😱 and fallen out of love with the S

the Chim does have a certain charm to it, but my S needs TLC, I`ll chase the boys on the cutter and see if they have an update, failing that it won`t take long with hand tools mate

Steve,

I think Mark was asking if you've become Chimerified.

But I think St. Athan is still a rebel S stronghold.
Beware the power if the Dark Side.

Mine is playing up too, 12v on battery, turns over very slow battery showing hardly anything while turning over [from cockpit]. Battery then about 11v after 1 try wont even turn. All starts and runs fine with jump. Was just going to change battery but could this be a bad earth? battery is only 18 months old car gets used at least twice a week.

The S is a little bit poorly, doing silly shifts at work has cut down the available hours of tiv maintenance. I must admit that I`m itching to get the growler up and running again, soon ?

Put a meter across the battery terminals to see what voltage you have, 12 volts should suffice. Then start the engine and measure the voltage at the battery again, it should read higher. I suspect though that your battery is on the way out.

Not so easy as this, unfortunately; you could get 12v through a wet finger but not enough current to turn over an engine. I'd say that if you had connected the jump leads to the tiv battery connections and it started, you have a duff battery.

Battery is under warranty anyway so will go back to garage where had it from tommorow.

A good charged battery should show about 12.6 volts with the engine off. One problem with lack of use is sulphation of the cells which prevents the battery working properly. They can sometimes be recovered with a long trickle charge. Worth a try before you rush out and buy a new one. If you buy a new one go for one of the calcium batteries, most manufacturers do them. Bit more expensive but they stand infrequent use better and normally have a 4 year guarantee.
