Car Forum / MINI / November 2003Indicator/hazard fault
I have an SPI cooper 1993 that has a recurring problem with blowing the inline fuse for the indicator, hazard warning and interior light. The car has an original fit rover alarm that is supposed to flash the indicators when it is armed. If I fit a new fuse and test the indicators etc while stationary they all work ( engine running or not) the interior light also works ( passenger door doesn't work) but if I drive the the car the fuse blows immediately. If I arm the alarm it arms and the indicator on the dashboard works but the exterior lights don't flash. I have wiring diagrams in the Haynes manual for the interior light circuit and the hazard circuit, but it has nothing about the alarm. Does any one have a sugestion of where to look first to try to rectify.

On my 90' Mainstream Cooper, I had no rev. counter due to a blowing fuse that turned out to be due to the wiper motor park switch being faulty. Once that got replaced, not only did my wipers park themselves, but the rev. counter worked too. Hope you get it sorted mate. Taffy Always one to blow when your windscreen wipers ice to the screen without you realising - blowing the fuse for the rev counter and if memory serves, the heater fan as well. I wonder how many times I have done that ;) The Muffin Man > > I have an SPI cooper 1993 that has a recurring problem with blowing the > > inline fuse for the indicator, hazard warning and interior light.

First, you say the electrics are fine with the car running but when you drive, the fuse blows straight away. Are you saying that you start the car, then indicate every thing is fine... Lift off the clutch, and the fuse blows? That would probably be somthing moving in the engine bay and trapping a wire aginst the body. Is it more likly that you are operating another circuit when you drive, that you hadn't thought of? e.g. Reverse lights, brake lights etc. If the fuse was blowing as soon as it was replaced, then there are simple fault finding methods I could describe, but the fact this only happens when you are driving makes this difficult. > I have an SPI cooper 1993 that has a recurring problem with blowing the > inline fuse for the indicator, hazard warning and interior light. The car [quoted text clipped - 9 lines] > > Thanks I have replaced the fuse 4 times in the last week. the most recent time I started the car the indicators worked fine drove about 200yds to the first turning and they no longer worked. The time before I put the new fuse in at the garage and I didn't test the indicators but they didn't work the first time I used them. The time before that I had used the car several times and it had been through an MOT test, the last thing I had done when the car was stationary was set the alarm. The alarm didn't flash the hazard lights but did work the horn. when I went to use the car a few days later the fuse had gone. The first replacement was a week before this when I bought the car it was already blown. I hope this helps. As I said the interior light doesn't work on the passenger door, I've bought a new switch for this and will fit this to see if this is the cause. Any further advice gratefully received.

It's simply a case of undoing the little screw, removing the switch and give it a clean and then replace it. I believe the screw helps to earth it so this needs to be rust free too.

Disconnect what you think may be at fault, eg interior light then tape up the connections Replace fuse If it is then ok, the unit must be faulty. If not then you just saved yourself money on buying an interior light you didn't need ;) My money is on the wiring loom that runs along the front of the car being rubbed through and shorting to the body. > > What size fuse are u using? > > [quoted text clipped - 119 lines] > >>>> > >>>>Thanks I have again replaced the fuse today and cleaned the contact on the pasenger door switch. My guess is that the problem is something to do with the alarm system as the fuse hasn't blown yet. I am avoiding using the alarm system at the moment. I think I need to know where the alarm is located and how it is wired in.
