Ballast Reisitor


Recommended Posts

Just wondering if it is possible to tell through obervation if the ballast reisitor is bad. My dilema is this, RHS fan not working when A/C is on, however I recently replaced NS radiator and am wondering if there is any possibilty I've messed somthing up.

I now there is a hack but on RHD cars the two relays aren't as easy to access so I'm worried about shorting somthing out. I have checked the fan and its ok, ran a 12v supply to it. If the reisitor is in series and is there only to provide a slow running cycle for the fan can I bypass it with a parallel connection? if it works I know its the resistor? you thoughts appreciated.

Hi Maurice, thanks for that, I've seen this before, problem is in the RHD cars the 2 relays aren't as easy to get to and at £60 a pop I wanted to see if there was another way to be sure it was the resistor.

Thanks, Tim

Tim:

Don't know if the relay tray is in the same (but opposite side) location, but when I had to rewire some terminals behind the relay tray I found it relatively easy to access the area of those four relays by FIRST removing the black plastic panel that surrounds the fuse block.

I have instructions on how to do that on Mike Focke's Boxster pages, in the section on Tops, and more specifically the write-up on how to install an OEM glass windowed convertible top on the early Boxsters (97-99). I think it's in section III, which describes the wiring process behind the relay tray.

Regards, Maurice.
