Need to add an earth (ground) symbol int word document

no. as long as you ground it by a mounting bolt. Might be pointless though. For your alternator is already grounded to the chassis. the alternator is grounded directly to the engine, the engine is grounded to the chassis. therefore your alternator is grounded already to the chassis.

Add one for safety, a ground is always a good with electric

ALTAI PWR MIC - black/braid= earth, red=RX, white=TX, Yellow=MODASTATIC - blue/braid=earth, black=RX, red=TX, white=MOD, Yellow=Spare
SIRTEL ECHO MIC CBE 2002 - black/braid=earth, blue=TX, white=RX, red=MOD007 POWER MIC - brown/braid=earth, green=RX, white=TX, blue=MODSADELTA EC 980 - braid=earth, green=RX, brn=TX, white=MOD
or braid=earth, black=RX, blue=TX, white=MOD

Do you have int wipers? If so check the int module its under the dash right side of the steering column I believe. Specifically check the solder joints.

It goes to the motor and grounds the ignition that gives it power. looks like yours has just came loose for some reason.

I understand the pain and how difficult it is to work on a science document!!!!!!!!!!!!
By the way if you are using the office suite applications such as Word 2007 or word 2010, you can insert the symbols easily.
To insert a symbol or special character into your document, follow these steps in Word 2007:
1. Position the cursor where you would like to insert the symbol or character
2. Open the Insert ribbon
3. Click Symbol in the Symbol section
4. A menu will appear with a small selection of symbols
5. If you don't see the symbol or character you'd like to insert, click More Symbols
6. Use the controls to select between symbols and special characters. Additional tools on the symbols tab will help you expand or narrow your selection
7. When you find your symbol or special character, click it and then click Insert
8. When you're done, click Close
The symbol or special character will appear at the appropriate place in your document.
Hope this helps!!!

Well, I am helpless regarding developing a keyboard with all those scientific symbols,.LOL
W

positive is your power input from 12 volt source.
the light symbol is the power out
Earth- is your ground wire

The earth wire ( ground) is only used to earth metals on/in the appliance.
If the appliance is double insulated ( I suspect it is ) you can safely cut off the ground wire.
You can identify the system used by 2 squares symbol, one inside the other which means its double insulated
