Rob;

...a bit sparse on info!

1. Why were fuses blown? They don't blow without a good reason, and that may be part of the problem...indeed Tach is powered by F4 in a 73 1800ES. Ref Wiring Diagram: https://www.sw-em.com/1800ES_73_Wiring_Diagram.jpg

...and unclear!

2. "condenser as i thot i had open circuit"...a condenser is ALWAYS and supposed to be, an open circuit!?!? Ignition troubleshooting info: https://www.sw-em.com/Volvo%20Ignition%20from%20Scratch.htm#Troubleshooting%20IGNition%20System

Tach wiring info (see Gen 3): https://www.sw-em.com/Smith's%20Tachometer.htm#Smiths_Tachometers_Gen1_vs_Gen2_vs_Gen3

"i did not replace tach, its still out of the car," Tach is in the Ign primary circuit, and without it wired in-place to complete circuit, Ign will not function...

Good Hunting
