'90 Eunos Heat and Charge Light at the same time

[ywouldi]

Hi all,

I have an intermittent fault it seems. Every now and then the Charge and Heat lights will light up, sometimes for a while but other times flicking on and off. The way that they act (i.e. coming on together) plus the fact the battery is fairly recent makes me think that it's not the CAT and Alt/Bat at fault.

Any ideas people?

Thanks,

Ben

O/T What is the heat light for? Don't think mine has ever come on!

You can read any fault codes yourself for minimum outlay and a bit of time/effort:

I'd suspect a poor earth / connection.

What's it for? My manual is in Japanese!

The heat light is to warn you that the catalyst has overheated. It only works once so once it's blown the light stays on. Largely pointless and if yours has never been on you're either unusually lucky or a previous owner removed it. Only fitted to Japanese/far east Eunos models

Cheers - mine's had a new exh. inc. cat at some stage so maybe reset/sensor removed...?
