Cat overheat light?

[kapri]

Hiya, me again with a Figaro problem. Does the March have a Cat overheat warning light same as the Figaro , I'm told they have a fusible link that blows if the cat gets raw fuel or the car misffires ( mines done both ) and it causes it to burn out and it's a riduculously priced main dealer part only ? Anyone found a way round the problem if we do share this part ?

cheers
Kev

mine has the wires to the sensor somehow joined or something (dont know exactly) as mine on the ST has the light but never comes on and the cat and sensor has been removed
