Sagaris dash light stays on while keys are out of the car
Discussion
Hello, I have an electrical problem with my Sagaris.
Last week I left my Sagaris in my garage and by accident I left the ignition on. About 8 hours later, I saw that my dashboard was lit and I turned off the ignition and took the keys out. At that moment the lights on dashboard went out so all fine I thought. The next day I saw that the dashboard was lit again while the keys were out of the car. I put the keys back in and tried to start, but the battery was drained. I then recharged the battery and the dashboard lights up again when I connect the battery while the keys are not in the ignition. Somehow, the ignition keeps staying on even though the keys are out of the ignition. I then removed all the relays one by one to see if the dashboard would turn off. This could mean that the starter relay is sticking. All the components connected to the relevant relays are working properly. All relays are fine but the dashboard light stays on. I have also checked the fuses and they are all good as well. I can start the car normally, but when I turn it off and take the key out of the ignition, the engine keeps running. If I disconnect the battery, the engine stops. The large 80A fuses at the battery and footwell are fine. I have also checked the ignition switch and it is fine too. I think the alternator is also fine because it charges 13.7 volts. Can someone give me advice and tell me what is going on here? Kind regards, Wim Waardenburg, The Netherlands

My money is on the alternator diode.
They get a thumping and breakdown over time.
Cheap as chips to replace.P600A diode inline with the B+ wire.
Make sure it's the right way round (-ve facing the alternator).
Depending on which alternator you have in the car you may need to hunt around for the old one.
Not sure where they are on a Sag.
I checked the alternator diode pack and they are fine. dashlight stays on when battery is connected and keys out. do you have more suggestions ?They get a thumping and breakdown over time.

I m probably way off, but .
Is it just the dash lights or is it all the accessories that stay on with the key removed?
I borrowed a transit years ago (same key I believe?) which I could take the key out of the ignition barrel at any angle of rotation, I only realised when I didn t quite turn it enough and the radio stayed on.
This was a very worn key/barrel though, so, as I said, I m probably way off.
Edited cos I seem to have lost the ability to use words today .
I will check. thank youIs it just the dash lights or is it all the accessories that stay on with the key removed?

It's not the diode pack you want to look at - it's the in-line diode in the thin B+ lead on the alternator.
This prevents a circuit being made between the battery +ve heavy duty cable connection from the alternator output to the battery and the B+ lead that connects to the dash battery charge low warning light.
ok I will check the inline diode. thank youThis prevents a circuit being made between the battery +ve heavy duty cable connection from the alternator output to the battery and the B+ lead that connects to the dash battery charge low warning light.
