24v warning light

pussa13 · Apr 9, 2012

Hi all hope you can help, after re fitting a radio in my 90 2.5td I have a 24v warning light on the dash, I've never had it come on before, can anyone tell me what it's for, and if it will cause any problems,how do I turn it off.
Thanks for your help.

Why mess about? Take the battery out.....better to be sure

Is that the one that is used for coverting 12V into 24V when radios are fitted?

A clue might be that you run a 12V system if you only have one battery, and the 24V warning light on the dash is there just in case you want to blow something up by putting another battery in series with the one that you had to start with, if that makes sense.

My 24V warning light is connected to the heater timer, as I couldn't be arsed to replace the original wiring.

I learned a lot being the second cousin of Beau Gueste ... You can call me Beau Nidle!

Just an update, I had not got round to removing the bulb untill today, went to try and start it nothing! flat battery. Would the little bulb on the dash flatten the battery in just a few days?

Not if your battery was OK.

I'm still confused with this 24v light, the light went out as the battery went flat but when I went to start up the heater plug warning light came on as normal but she was sluggish to turn over, so I charged the battery over night, when I went out this morning the 24v light is back on!! I need to find out what controls this light so I can try to isolate it.

Do you have a 24V system or a single battery?

I looked at one recently and found a second battery hidden away under the tub which, at one time, had been used to run a 24V ex-MoD radio!

If you only have one battery, check the voltage going to the lamp and then trace it back using a meter and the wiring colours. Once you have found out where it is fed from, and assuming that it is surplus to requirements, you should be able to isolate it at the source end.
