Peaklander posted a topic in Defender ForumHi all, I run a 300 TDI 110 CSW 1996 and I wonder if anyone has had a similar problem to this one. I have purchased the Bosch relay (0986335058) to provide an adjustable delay on the intermittent wipe for the front screen. It's a direct plug-in for the existing relay behind the fuse board in the cab and it's something I've known about for a long time and finally I bought one. It's a £40 upgrade so not cheap. It's a straight plug in, nothing else. However I can't get it to work. I can't set the interval and it will do multiple wipes - like two , three or even four. If I replace the old one I get the standard two / three seconds so I don't suspect there's a wiring fault. The supplier very willingly sent a replacement but this behaves in exactly the same way, so it can't be the relay. I have a healthy battery etc (I have a Fluke voltmeter so I know that battery volts are OK). At least 12.4v with no engine and up at 14.1 / 14.2 when charging. I'm beginning to suspect that there must be lower volts at the relay base (than at the battery terminals) and that this might affect the delay circuit (electronics) in the new relay. I hope to get chance to have a poke about with a voltmeter on the relay pins tomorrow. However I just wondered if anyone has any ideas or experience of this? Thank you
