Fuse blowing on Mitsubishi L300 2.4l motor, manual gearbox. Fuse 15, indicators, fuel guage, tacho. Found to be short in reversing light switch in gearbox. Initial disconnect of switch stopped fuse blowing, renew switch restored reverse lights
Their is a reverse light switch on the top of the gearbox or the front of the gearbox which depends on which make of gearbox you have one german and one english if i remember rightly ,pull the connection plug off the top of the cwitch and push a paper clip between the two contacts ,turn ignition on and if the reverse lights light up you know the problem .simple
The reverse switch is located on the gearbox and has two wires attached to it, probably with spade terminals. (It looks like a pressure or temperature switch) Pull off the two terminals and touch them together. With the ignition on, the reverse lights should now function, unless your problem is elsewhere like in the wiring etc. If you replace the reverse light switch watch that it is not below the gearbox oil level plug. If it is, the gearbox oil will drain while the switch is out.
no i think your problem is the reverse light switch in the gearbox or the bulbs but your dealer is trying to give some fairy story to turn a simple job into a major rewire or something ,either that or they employ monkeys because they only pay peanuts .ask a local mecahnic to check it out for you ,look for a feed to the reverse light switch on the gearbox first ,then if a feed put a paper clip across the two wires and see if the lights come on ,if they do then just renew the switch ,if no Supply then make one ,find fused ignition on supply in the power distribution box under the bonnet and run this to the switch and away you go --- simple .Problem with dealers is someone has to pay the gelled up nancy boys in suits who are so called salesman ,and not forgetting the barbie doll secretaries and the managers free company car .whos paying for all this??
There is a switch attached to the gearbox which activates the reversing lamps when you place the gearbox into reverse. This switch has two wires going to it, one wire is an ignition live feed and the other is the feed to the rear lamps. This switch is usually on the side of the gearbox but quite high up towards the top of the gearbox. You can remove this switch with no danger of losing gearbox oil and replace it. Using a test lamp (which you can buy from any auto parts store), connect the end with the clip to the body on a clean area to ensure a good electrical connection and the pointy end to each of the wires on the switch in turn. With the ignition on but the engine NOT RUNNING, one wire should be active and the other will become active when the gearbox is placed in reverse gear. If neither of the wires are active, check fuses etc. If one wire is active but the other does not become active when reverse is selected, replace the switch. If both wires do what they are supposed too, check the wiring from the switch back to the rear lamps and check for broken or disconnected wires.
The switch can be accessed from underneath the vehicle. Remember that these tests are conducted with the ignition turned on but THE ENGINE NOT RUNNING....
