i have a 1983 suzuki sj410, which i just discovered the indicators dont work, but the hazards do, i then discovered the wipers dont work, neither do the reverse lights or the washer motor, i also dont have high beam headlights but i do have low beam. Any ideas people???

I'd start with the fuse box. Check not only the fuses but the wiring to the fuse box too. Then work through each problem from there.
My 410 FSM shows the Wipers, washer, reversing lights and horn to all be on the same fuse (yellow wire). Main beam could be the bulbs? a bad connection or maybe a bad switch.
