I have just joined
Wondering if there are any 1st gen classic owners about?
I purchased mine as salvage but have rebuilt the hv battery and now all good but classic prius seems to be a bit rare in the UK.

I’m in the US, and I also own a Gen 1 Prius. 2002. It has been hard to find parts for it thus far. But I had a hunch that the catalytic converter for 04-09 models would work w it, and it did.
I like the car, but not sure I have the time and knowledge to repair the last couple problems with it. The engine speed alternately races then idles, usually when I just start driving it. Seems battery-related, but I haven’t had the time to determine exact cause.

Have you used diagnostic on it? Doctor prius app should highlight battery issues
Mine has earth strap that was corroded which caused cutting out and battery malfunction messages.
I replaced 2 battery cells and cleaned all connections been ok since.

What diagnostic? I’ve not heard of
a Doctor Prius app.

I also replaced the ground wire
(on the aux 12V batt). Didn’t help.
And cleaned the oxidation off the
positive terminal & pieces. It seemed
to help a bit.

Now I’m wondering if my voltmeter
is accurate.

Thanks for the suggestions.
