My decat broke and my battery and cat light came

I replaced the downpipe and have the lambda sensor in and no cat temp sensor,

Is this problem related to the alternator?

Really wanna get this sorted and it's not affectin how the car runs if it is the alternator I'll just replace it.

Sounds like it bud what u need if got one get a volt meter and put it across the battery and see if it reads 14.5 volts that way will show that the bat is being charged by the alternator

Will that throw up the battery light and cat light on the dash bud?

Sounds more like a broken engine ground to me...

So just an earth wire somewhere?

Also I have a new battery also as the last one went flat I noticed last time I was drivin it the clocks illumination was going dim?

Is that an indication to the alternator also? Or would a bad earth drain the battery? Not to clued up on car electrics lol and im a overhead linesman haha

Check earths and the alternator that way cover ya areas

Put meter on battery anything around 14v is normal. (when its running).

To check current drain you can use the finer settings on the meter to check the current being drawn.

If you can't get rid off them lights you could always try removing both terminals OFF of battery and hold them togethertis will totally drain the power from the car.

the battery light comes on with the cat light so seem to be something to do with the cat temp sensor maybe faulty you dont need it you dont have a cat just disconnect it.

just read you dont have cat sensor connected, maybe the wire is shorting/touching the gearbox somewhere.
