Triumph TR6 - Ammeter

Could a faulty ammeter cause a complete electrical shut down? ie. no starter no lights, nothing. As a temporary fix could one safely wire around the meter. The wireing diagram shows two brown/white wires on one side and a white wire on the other side. Any suggestions.

Question 1:The short answer is yes.
The long answer is: Power from the battery is to the starter motor to the ammeter (Large Brown wire not white) then splits from the ammeter ( 2 wires both Brown/white) to the alternator and to the ignition switch...from the ignition switch to the light switch. Remove the ammeter and nothing happens.
Question 2: Can the ammeter be bypassed..the short answer is yes.
The long answer is.. this is not something I would want to do. I would only have this situation long enough to get me home and replace the meter. You are inviting an electrical fire under the dash. Consider this "bypass connection" is drawing full power through it at engine start. The temporary connector must be same guage as the larger brown wire not the smaller brown wire. I would even solder the 2 wires together if I could to get me home.
Greg Temporary fix is said here only if u are currently on the road and are using someones computer to access this BBS to get an answer. If you are at home, then replace the meter and do not do a temporary fix. If you still want to do the fix/bypass then make sure your passenger is a fire extinguisher!
