Technical Punto grande steering stiff and battery light on

[Pedro6]

hi I have a 2007 fiat punto grande, battery light comes on and steering wheel goes hard soon as turn it off n on again it’s fine replaced alternator but no luck soon a few people with same problem but never has a answer. Also I have a engine light on unrelated I think with a undocumented code ? Any advice would be great thanks

Have you replaced the Negative battery to chassis cable.. ?
they can break down internally and cause power supply niggles

Cheap to replace too

As others have suggested, it would be well worth checking the health of your battery. If you don’t already have the necessary equipment, retailers like Halfords will offer a free check. Independent battery retailers are likely to do the same.

I’d also be tempted to buy a cheap OBD reader from Amazon or similar and scan for any error codes. I mention this because I experienced similar issues when our Punto’s power steering motor started to fail.

I’m not saying yours is too, but at least you can rule it out.

@Pedro6

You can use a 'jumplead' battery negative to engine metal .. as a test for that earth cable

cheers will try these things out, I did scan for codes for the engine light but it’s down as a “undocumented code” never get the chance to scan when battery light comes on tho

Let us know how you get on please.

Out of interest, are you using MES to scan for error codes? I’ve found the generic apps don’t offer much when it comes to Fiats.
