    Default Wanted: Black Box!

    I have a 2015 Caterham 7 280. The turn signals and hazzard lights stopped working a couple of months ago. My mechanic traced the problem down to a black plasticbox about the size of a cigarette pack, but Caterham parts says these are back ordered in a serious way. Does anyone have one they would be willing to sell? If so, for how mych?

    I suspect one of the U.S. Caterham vendors will have one, have you tried (Beachman Racing, Rocky Mountain Sportscar, Sevens and Elans).

    Try flipping the Hazard Switch off and on several times. I seem to recall this being a common problem and the UK lotus 7 guys on blatchat found this to be a solution. Worked for me once when mine failed like yours. Good luck. Tom

    Also check that all wires are plugged securely into the alternator! I had the same problem and a loose alternator wire was the issue!

    AS mentioned before, this has been addressed on "BlatChat" in the past. I "fixed" mine by flipping the light switches and the turn signals along with the Hazard switch, back and forth many times. It is corrosion in one of the switches, and I NORMALLY don't use my lights or flashers very often. OF course, I use my turn signals often, and you must flip the switch ON and then flip it off, as it is not self-cancelling. It was NOT the turn signal switch, in my case.....
