Anything to be concerned about? should I use a higher amp fuse? a 30amp? '57 235cui

I definitely would not put a bigger fuse in. | | | | | Joined: Feb 2004 Posts: 29,871 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,871 | Has the system been operating normally before the module change? It sounds like you've got a dead short somewhere, or maybe an incorrect wiring connection. It's not unusual for a HEI system to draw lots of primary current, but a 20 amp fuse should carry the load OK. I'm not familiar with that system- - - - -which distributor and module does it use as the basic unit?
