So after 8yrs away from cosworths I finally buy another...2wd sapph...lovely bodywork but suffering from electrical gremlins...I need help please! So far I faced with...

1) left hand indicators comes on (not flashing just permanently on) when I turn the headlights on and if I try to use the hazards it actually makes a weird dieing buzzing noise and nothing happens? Right hand indicator works fine.

2) no rev counter although the car is running wasted spark so I'm guessing it's related to having no dizzy??

3) Battery light comes on randomly and then stays on even though I've got good 14v returning to the battery?

4) no water temp gauge working

I'm sure I'll find more...going to take the clocks out and have a look behind...

I forgotten how much "fun" cosworths are..🤣🤣
