"My 88 Caterham has an odd indicator problem I have not seen before in tech talk. When switching on either left or right, the opposite side comes on at about 1/4 - 1/3 power also. I suspect the the hazard switch because the hazards were causing the flasher to buzz instead of switching until I actuated them several times. Now they work, but can't get the indicators to behave. Suggestions?" That sounds like the common problem inside the rocker type hazard warning light switch, and I'd start with exploring that. There's a *full explanation in the archives, but you can sometimes localise the fault by working the switch a few times and seeing if that has any effect. If it does then you can open the switch and clean the contacts. Or buy a new switch from Redline. ... The next most common problem is probably the indicator unit ("relay") and its connections. Inspect the pins and check the seating. Then try another unit. ... Jonathan * Why it causes the strange effects, and an improved circuit design that removes the problem.
