no spark on merc 260

[RickBomba]

Hi,<br />Can't seem to get a spark on my rebuilt merc 260.<br />So far I've tested shift interrupt switch...fine<br />All connections to distributor...fine<br />I'm not getting voltage across the coil when ignition's on.<br />Only thing I can't test is ignition amplifier (thunderbolt 4 ignition). Reluctant to buy new one b/c part is $300 and i am not 100% that this is the problem. All connections are good and batteries are brand new.<br />Any help would be greatly appreciated.<br />Thanks,<br />Rick Bombardier

<br /><br />Disconnect the purple wire at the + side of the coil. Run a jumper wire from the + side of the battery to the + side of the coil and see if she starts. Remember you will have to disconnet wire to kill engine. This will let you know if amp is good.
