A few pictures, one is the circuit of the viabrator in Ign coil test, not included the amp meter in the circuit. Also one of the viabrator (one half of the armature had fallen off) I soldered it in place & now works.

Reviving this old thread yet again - I've just picked-up a 98 and I'm looking to replace the 7.5v battery with a power supply. I'd like to internally tap off of the incoming 110v hopefully using one of the cheap 7.5v video game power supplies you can find on eBay. Can somebody tell me the A/mA requirements for the 98?

I'd also like to beg for a copy of the manual (hopefully with the 70's updates) if someone could point me to the right person - the link in #11 above isn't good anymore.

Thanks in advance for any help.

Hello again:
Still in search of a schematic for the elusive Mercotronic model 98 ignition tester. Has anyone in cyberland found one yet?? If or when I do I will certainly share. Please give me a shout if you find one. These are great for servicing early ignition systems.

I gave up and finally broke-down and bought one from an eBay vendor - $25; there are a couple still listed currently.
