Narrative:

On takeoff I took throttles at 80 KTS. At about 125 KTS I noticed right amber reverse in transit lights (757 glass) I aborted takeoff -- went to gate with reverse isolation caution light on. Maintenance locked out right reverser. We waited 85 mins cooling time and went out again. At about 300 ft the left reverser in transit illuminated and likewise right intermittently -- then, above 400 ft all aircraft caution and advisory lights flashed on and with gear up, they lit up all green down and locked. I was about to turn back with all connected except EICAS 'left reverser isolation unlocked.' obviously a problem with computers. At pbi they replaced the ground interlock relay computer box and that apparently fixed problem. Frequently, in glass cockpit, we get transient faults that connect -- that's why I elected to take full ship to pbi uneventfully.

Title: SEVERAL FALSE WARNINGS BEFORE AND AFTER A TKOF ABORT.

Narrative: ON TKOF I TOOK THROTTLES AT 80 KTS. AT ABOUT 125 KTS I NOTICED R AMBER REVERSE IN TRANSIT LIGHTS (757 GLASS) I ABORTED TKOF -- WENT TO GATE WITH REVERSE ISOLATION CAUTION LIGHT ON. MAINT LOCKED OUT R REVERSER. WE WAITED 85 MINS COOLING TIME AND WENT OUT AGAIN. AT ABOUT 300 FT THE L REVERSER IN TRANSIT ILLUMINATED AND LIKEWISE R INTERMITTENTLY -- THEN, ABOVE 400 FT ALL ACFT CAUTION AND ADVISORY LIGHTS FLASHED ON AND WITH GEAR UP, THEY LIT UP ALL GREEN DOWN AND LOCKED. I WAS ABOUT TO TURN BACK WITH ALL CONNECTED EXCEPT EICAS 'L REVERSER ISOLATION UNLOCKED.' OBVIOUSLY A PROB WITH COMPUTERS. AT PBI THEY REPLACED THE GND INTERLOCK RELAY COMPUTER BOX AND THAT APPARENTLY FIXED PROB. FREQUENTLY, IN GLASS COCKPIT, WE GET TRANSIENT FAULTS THAT CONNECT -- THAT'S WHY I ELECTED TO TAKE FULL SHIP TO PBI UNEVENTFULLY.
