Got one in a HQ, just went to start it and theres no spark. Only thing I've done is just put a new battery in it . Does the MSD box have an internal fuse which may have blown, or is it likely to be something else!

Have you had the unit running before!No internal fuse.Check out msd's website,they have a good troubleshooting section.

tell me you didnt put the battery in wrong way around !

Mine did this intermittently even when driving along then would magically fix itself 4minutes to a week later (convenient I know). I landed up buying a new one cause I never figured out why it did it.

Na didnt put battery in back to front, have checked the box and coil and have got plenty of spark there but doesnt seem to be getting to the dizzy or from the dizzy to the leads.

How do you know you have 'spark at the coil' !
If the coil is working, then surely the issue would be with either the HT leads, or the dizzy! Did you touch any of the distributor wiring!

Done the MSD test on there website, coil and box are fine.
