Hi Guys

Right i have just got together all the parts to get my 1275 Running and am about to do so.

i have bought a cheap front subframe that the engine is mounted on and that in turn is bolted to the table so it isnt goin anywhere. my question is this.

obviously i have to link up the booster to turn the engine over this im guessing goes to the starter motor directly, but what am i doing with the Dizzy, HT coil and Spark Plugs and of course the alternator???


cheers

Why are you doing this?

[RobDupre]

lol long story

I only ask as it will effect giving you a worthwhile answer.

Is it to test before fitting/

How long are you expecting to run it for?

[Jimmyarm]

If you want to run it for any length of time, dont forget you will need to attach the radiator too as well as a system for venting exhaust gases out of where you are working as well as a safe source of petrol (having an open tub with a hose into it is a bit of a no no)

The ignition system should be all be put on as it would be, it wont run otherwise !

If you just want to turn it over to test if you get oil pressure, then just get a battery and some jump leads and attach to the relevant points on the starter motor.....with the plugs out

[dklawson]

Do not hook up the alternator. The only reason to hook it up is if you plan to leave the engine like this and run it as a stationary power source for something else where you need to worry about recharging the battery.

You will need a battery and a starter solenoid. (Yes, you can use the booster to start the car, but I would not plan on running it with the rather noisy power coming out of the booster). Hook the battery earth/ground to the engine. Hook the battery (+) to the starter solenoid. Make sure the ground connection is good.

Put a single-pole/single-throw (SPST) switch in series between coil (+) and the battery connection on the solenoid. (This assumes you have a standard (and not ballasted) ignition coil).

Put a momentary contact, pushbutton (starter) switch in series between the battery (+) connection on the solenoid and the little spade lug on the starter solenoid where the ignition switch wire would normally go.

As mentioned earlier, provide some form of radiator or cooling and install a muffler of some type on the exhaust.

Place the SPST switch in the "on" or "closed" position (this is important... if the switch is open for the "off" condition... the engine will not start). The SPST switch must be closed to power the coil. Press and hold the pushbutton to spin the motor over on the starter. If it's all OK, the engine will catch and run, drawing ignition power off the battery.

To stop the engine, throw the SPST switch to the "open" or "off" position to remove power from the coil.

I would also recommend having an analog oil pressure gauge fitted...

thanks guys loads of help!!1

yes it is to test the engine and also to see if the work i have done to get it running gain has worked!!!!!

cheers i will let you know hows i get on!!

[Ethel]

You could have saved DK some typing if you said that first off!

You'll gain nothing by running the engine, just get the plugs out and crank it on the starter till you see oil pressure and have a good look round for oil leaks.

You shouldn't start an engine until you know it has oil pressure, it doesn't take very long to trash one that doesn't.

You can use a compression tester if you like while you're cranking it over

Best to turn it by hand first to be sure nothing catches.

But to crank the engine on the starter im still going to have to wire it up to either the booster or use DK's Wiring System.

I will test for oil pressure before i actually start it though.

thanks for the help

All you'd need is a battery across the starter (big is good, it takes a lot turn an engine for any length of time - be prepared to allow it to cool too)

No ignition, no fuel, cooling or ancillaries all of which can be sorted equally well once the engine's back in the car and it will be back where it belongs sooner if you don't put your efforts into motorising your garage workbench only to rip it all to bits so you can put it back where it belongs!

Bet that sounds way too aggressive but I am only trying to save your time and effort.

no its okie i understand but your assuming i have a shell to go along with my engine lol
