i recommend it to be grounded, but mine was not grounded for years and still worked. if you don't ground it it may cause damage to the coil tho

Does the ignition coil need to be grounded on a 2003 Chevy Astro?
It is advisable to have the ignition coil grounded on a 2003 Chevy Astro. This should especially be done when you are working on spark plugs and wires.Ê
How do you connect battery and coil in a 1950 dodge wayfarer with positive ground?
make sure the coil is a positive grounded coil, most are negative ground. battery just hooks up opposite to usual the coil is the only thing u need to make sure of
1986 fifth avenue 2barrell elb2 your coil won't fire it is getting voltage and the pickup coil is new if grounded momentarily it runs so what's wrong?

How do you test a motorcycle coil that has two leads and is not externially grounded?
Basic coil tests are for Primary and Secondary ohms (resistance) values and I.B. or an Insulation Break meaning you have a short. Refer to your owners manual for what type of coil you have. Different models have different ohms ranges. This test would be for a typical 3-5 ohms single lead externally grounded coil. You can usually identify an Externally grounded coil as they are grounded by the mounting fixture itself. TOOL REQUIRED - VOLTMETER that will read ohm values 1. DISCONNECT THE BATTERY NEGATIVE CABLE 2. If the coil is in the bike disconnect wires from the two terminals to isolate it. 3. Once you set your Voltmeter scale to ohms connect the red and black leads to each terminal. You should read between 3 and 5 ohms if that is the spec for your bike. You have now tested the primary circuit of your coil. If you read Infinity ohms replace the coil, you have an open circuit or break in your coil winding. 4.Now take your black lead off one terminal and connect it to good ground, battery negative cable or non-painted frame bolt. Your meter should now read 0 or OFL (off line). If you do get a reading here your coil has a break in the insulation and is shorting out. Your only option here is to replace the coil. 5. Repeat step 4. for the other secondary terminal. Red on terminal, black to ground. It should also read OFL. Another quick test option regardless of type of coil is to check Volts going to the coil with battery connected. If you have a 12vdc system and you are getting close to 12vdc at the coil terminal and nothing is coming out of the coil you either have a bad coil or connection.
Where is the negative coil wire in a 1986 Chevy Monte Carlo?
First find the coil it should be close to the distributor you will have two little screw post on the Coil it self. If you will look real good it will have a pos + terminal and the other post will be your neg - terminal the coil will be sitting in a grounded holder.I hope this will help you find what your looking for.fatdaddy466
Why does your coil fuse blow when you try to start ignition?
You have an electrical short. It could (possibly) be a short internal to the coil but it's much more likely that a wire (somewhere between the ignition switch and the coil) has rubbed through against a bit of (grounded) metal. Look for any wire rubs especially near the coil and/or near the throttle lever.
What would cause no spark from the distributor on a 1994 Chevy truck?
Dead battery, grounded or open central coil wire, bad rotor, or corroded connections. Could also be a bad spark generator--the coil analogue in an electronic ignition.
How did Shane filan killed Bryan mcfadden?
Because Brian McFadden was naughty, and Shane Filan told his Dad. Then Brian's dad said "That's it, you're grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded. Go to your room. NOW!" Brian then cried to his room, only to jump out of his window, then onto a tree. Then there was Shane. Shane had a gun, then shot Brian. Brian McFadden died.
Can a bad ground on the coil result in no power to the ignition?
Maybe With out make model and year info here is a back ground answer. Most Modern Electronic Ignition systems operate by controling the ground for the ignition coil. These ground conections are "Common" or all hooked together. If there is no ground for the coil, there is a good chance none of the ignition is grounded correctly.
Does a 2000 model 4.6l f150 coil have to be grounded to the block in order to fire?
it depends if you want to risk it then yes. If not then no. Usually u would just fire of the ground to not damage the gun
No spark on right bank for a 1982 kawasaki csr 305 coil is good?
The problem sounds like a possible faulty condenser, closed or faulty points, grounded points lead.
I changed the coil on my 1980 Honda cm400 so why im i not getting any spark to the plugs?
Here are possible causes of no spark on the 1980 CM400, starting from the easiest to fix: kill switch turned to "off" position. Bad spark plugs. (It's important to be aware that on this bike, both spark plugs must not be fouled; If either one is fouled enough not to fire, there will be no spark, because the way the system is designed it takes both plugs to complete the ignition spark plug circuit.) Kill switch malfunction, causing the coil to be grounded. Ignition switch malfunction, causing the coil to be grounded. Bad Coil. You've presumably eliminated this, but consider the possibility the new or used coil you obtained could be bad) bad pulser coil or stator. (follow instructions in the shop manual to test these, the manual is available all over the net in .pdf)
