I can solder them no problem, I just don't know where to solder them to! lol

Does it not matter which way around you put the positive and neutral wires?

I never use them..... the whole point of a brake in is to allow the piston and sleve to warm up and cool down together. Of cource they do make starting a tad bit easier, but if a nitro engine is tuned correctly then it'll start quickly anyway....


Some dont some do.... there mainly used my racers so there engine are kept hot untill the race starts.

I had a Schumacher rascal for a bit over a year, tuned sweet as a nut, broke in and had a good coupe of gallon thru it, it was still as tight as a gnats chuff and had to be pre heated on all but the hottest days... All engines are different.

If you can pre heat, do so, saves wear and tear on a host of parts... and the skin on your fingers too!

+ to centre contact  - to side springs. My 12v plug had holes drilled into the contacts so I threaded the wire through then soldered them.

Cheers mate. So is where I've put the crosses ok? There will only be two wires as it was suggested I solder two positive wires together to get the main beam to come on on the bulb. My electrical knowledge goes about as far as wiring a plug, so excuse my ignorance.

Looks fine. Just make sure the wires don't short out on each other.

Ok. to start with the bulb doesn't care which way around you connect it so long as each element is connected to a positive and negative connection.

The twin element car bulbs have got a common earth (negative) connection, so the job of joining them together is already done for you.  On my bulb connector, the common negative was the yellow wire.  This should be connected to one of the battery terminals.

So that you can choose which element to switch on, the bulb has two positive connections (one for each element).  As we want both elements to come on (creates more light and more heat), you need to have both the positives connected to the positive.  On my connector this was the blue and red wires.  You need to connect these together and then to the other battery terminal.

As you can see on my one, I used a length of two-core mains cable to go between the bulb connector and the battery.  I used large croc-clips on the end of mine rather than a cigarette plug as I prefer to connect directly to the battery terminal and you might end up blowing the fuse in your car if you run the heater off it.  The heater will draw around 5 amps, so you might want to check what your cigarette lighter plug is rated for.  As mentioned in an earlier post, putting an in-line fuse in one of the wires would be a sensible thing to do as these things could easily short circuit and cause a fire if you're not careful in construction and use.

I built my own engine warmer out of a can of peas and a 55w headlight bulb. Takes about 10 mins to get my engine up to 185f.

clever dick. thats an awesome idea!
