Narrative:
Climbing out; we received a right wing 'a' ice valve ECAM. We were on autoplt at the time; so I pulled out the book. Then we received a 'standby pitot heat' fault. The book prescribed no procedure; just information on the nature of the fault. Then we received a landing gear shock absorber fault. It appeared that the airplane thought the landing gear was still down; because the ECAM told us to leave the gear down. Then the autoplt kicked off; followed by the autothrottle and flight directors. It appeared that we had also lost the #1 FMGC. We had multiple unrelated problems; spoke with dispatch and maintenance and concluded after numerous tries at a reset; that something electrical was failing on the airplane. With these multiple unrelated electric faults and failures; we elected with dispatch's concurrences; to go into ZZZ1. We landed there with no further incident; exchanged aircraft and continued on to ZZZ2. Callback conversation with reporter revealed the following information: the reporter stated the multiple unrelated electrical faults suggested the airplane had a wiring problem and the decision was made to divert. The cause of the multiple electrical faults is unknown as maintenance has made no report to the flight crew.

Title: AN A320 FROM CLBOUT TO CRUISE AT FL380 EXPERIENCED MULTIPLE UNRELATED ELECTRICAL FAULTS INCLUDING #1 FMGC.
Narrative: CLBING OUT; WE RECEIVED A R WING 'A' ICE VALVE ECAM. WE WERE ON AUTOPLT AT THE TIME; SO I PULLED OUT THE BOOK. THEN WE RECEIVED A 'STANDBY PITOT HEAT' FAULT. THE BOOK PRESCRIBED NO PROC; JUST INFO ON THE NATURE OF THE FAULT. THEN WE RECEIVED A LNDG GEAR SHOCK ABSORBER FAULT. IT APPEARED THAT THE AIRPLANE THOUGHT THE LNDG GEAR WAS STILL DOWN; BECAUSE THE ECAM TOLD US TO LEAVE THE GEAR DOWN. THEN THE AUTOPLT KICKED OFF; FOLLOWED BY THE AUTOTHROTTLE AND FLT DIRECTORS. IT APPEARED THAT WE HAD ALSO LOST THE #1 FMGC. WE HAD MULTIPLE UNRELATED PROBS; SPOKE WITH DISPATCH AND MAINT AND CONCLUDED AFTER NUMEROUS TRIES AT A RESET; THAT SOMETHING ELECTRICAL WAS FAILING ON THE AIRPLANE. WITH THESE MULTIPLE UNRELATED ELECTRIC FAULTS AND FAILURES; WE ELECTED WITH DISPATCH'S CONCURRENCES; TO GO INTO ZZZ1. WE LANDED THERE WITH NO FURTHER INCIDENT; EXCHANGED ACFT AND CONTINUED ON TO ZZZ2. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE MULTIPLE UNRELATED ELECTRICAL FAULTS SUGGESTED THE AIRPLANE HAD A WIRING PROB AND THE DECISION WAS MADE TO DIVERT. THE CAUSE OF THE MULTIPLE ELECTRICAL FAULTS IS UNKNOWN AS MAINT HAS MADE NO RPT TO THE FLT CREW.
