MR2 Terminal 30 Interrupted

I had a similar issue with my MR2. Check your charging system and ignition switch. Could also be a weird fuse box issue or electrical fault somewhere. Have you checked for voltage drops?

Where exactly did you find the voltage drop? Was it obvious, or did you need to chase it down?

I didn't find it myself, unfortunately. Turned out to be a corroded wire in the fuse box. I'd recommend taking it to a workshop; chasing electrical gremlins can be a pain.

Thanks for the tip! Workshop confirmed it - corroded wire. Cost me 290€ to fix. Much appreciated!
