Bongo Fury

Was told by my dear wife that the fullbeam was not working correctly, so I checked out the faulty driver side bulb, bulb fine, apart from being a 80 watt bulb that I am told is illegal. The problem is the 3 pin adapter that the bulb connects to, it has melted on one side and that is why the bulb is erratically working. I have replaced both the front headlights for correct wattage bulbs, but wonder what has caused the problem????? Pippin will know p.s. have ordered a replacement adapter from unifit, will I be o.k. connecting with a block connector?

The problem has probably occured from using a higher wattage bulb than is recommended pete,the higher wattage means a higher resitance also.

What's the story with the 3 pin adaptor? I assume you don't mean the original block that plugs onto the headlight bulb?

That is the fellow I hope to be able to repair tomorrow them bulbs haxve been in since we got the bongo, so running 3 years before any problems, they have got through 3 m.o.t's too

I see pete, so they have held up pretty well all things considered....

I guess you are chopping off the old plug,then connecting the replacement?

I'd suggest soldering and heat shrinking the new contacts pete,scotch block them as a temporary measure,i'm thinking of long term reliability here pete.

Sound advice, I will dig out the soldering iron Thanks Ste

No probs pete, hope it goes ok for ya... Just don't do my classic trick of forgetting to slip the heatshrink over the wire BEFORE the soldering is done!

A higher wattage wil have LESS resistance therefore more current. It's the current which the connector/wires can't handle.

Unless the connectors/wires are up to it all you can succeed in doing is have a slightly brighter lamp and lovely hot wires

Of course,i knew it was something like that....

Thanks guys, will remember the heatshrink Both bulbs replaced so hope the wires keep their cool, just like me after drinking my valentine wine

If the bulb was working erratically & the fitting melted I would guess that the connector had a dodgy connection, maybe oxidised, creating heat as it arcs across like a welder. Happened to a relay under the dash on my old 2.8 4x4 sierra, was smoking nicely, about to catch fire, just because of an oxidised connection

You are quite correct Obvious signs of arcing and oxidation on the connector I will be replacing

I think we've all been there at some time Some years ago, I remember soldering every connection in a 25 way D connector (old style parallel computer interconnect) and then realising the die-cast cover should have been slipped into place first

I fit a new bulb holder, had to fit with connector block, I was working outside and my poor little soldering iron could not generate enough heat to melt the solder So all wrapped up in gaffer tape, till the weather warms up a little

Just keep an eye on it pete,the tape should do just fine for the time being, i know hat you mean with the cold finger thing,i helped to fit two flushed fogs into dabs' bongo today, and my thumbs have just thawed out!
