clio williams 2 starter motor not responding?

Hi everyone I have just had the Williams jacked up on the ns for 3 days while I re welded the triangular section under the passenger footwell, I also patched the exhaust joint with EAP as it was blowing a little. So I go to start the car all lights come on fuel pump primes but nothing from the starter motor, and when I turn the ignition off i get a fast relay clicking from the fuse box and the indicators on the dash flicker a little, and also now when I go to lock the car( Clifford alarm, not sure make as I lost the cert) it locks then sets the alarm off! Prior to jacking the car up everything worked fine. Help much appreciated

Did you disconnect the battery before doing any welding ?

No I dident, I was doing gas welding, also while quenching the welds the passenger footwell collected some water but I dident see any wires around there?

Should always disconnect the battery when welding because the chassis is the ground for the cars electronics.

Fixed! Just a dead battery�� think there's a bad earth somewhere as its a new battery and shouldent drain that fast, thanks for the help everyone��

That's lucky! Glad it's sorted

That's cool :) in the future though disconnect the battery before any welding :winkey:
