I have a rascal taxi 4 and it wont go it has a light that flashes 5 times then a beak then again and again help meeee

Either your parking brake is engaged or if your scooter is more like mine i have a Rascal 600t it gives a code 5 service code when it thinks its in free wheel. The freewheel mechanism is located on the trans-axle which if you go outside across grass it gets wet. Th is device doesn't like moister and will get stiff will partially engage or disengage. In that mechanism there is a micro-switch which if the lever when slipped into the engaged position doesn't go all the way to the seated position the switch will see the mechanism as being disengaged [in free wheel] and will inhibit the motor from running. I lubricate the entire assembly with pure silicon spray oil,WARNING, do not use WD-40, It will eat some plastics.After lubricating the lever should move smoothly. I have to lub my scooter about once a month in the winter.

Now if this doesn't work check the connector that are all the wires are connected. Disconnect the connector check the pins are ok reconnect check to see if your still getting the failure. If you are still getting this problem do continuity checks on the wiring. You will need a multimeter only $9

Select ohms the highest scale, short the leads together, zero the meter by turning the zero adjust knob. There is only one wire we are interested in. On some scooters you can visually see the switch and the wire running from it. The wire usually foes to a spade connector. Disconnect the spade connector put a probe on that connector leading to the switch. Disconnect the battery put other probe on the positive side of the terminals that were connected to the battery not to the battery it side.Work the switch does the meter needle deflect to zero, no, try the negative side. Does the meter deflect, no, put the probes directly on the switch terminals, does the switch.when worked now cause the meter to deflect, no, replace switch, yes, the problem is in the harness, don't panic, use can use that meter to trace the wire through the harness. Wiggling wires and flexing connectors usually makes the meter flick at some point. Thats how i do it i'm never without my trusty meter. Rascal are notorious for having problems of this type my mid-frame harness fell apart in the middle of a six lane intersection, the scooter simply locks up tight .I can do nothing but sit in the middle of this huge intersection. People try to move me but the scooters wheels are locked, my illness makes it so i can't communicate with people do it was a mess. So i modified the connector so its no longer a latch type connector. I drilled it for a quick pin which is much stronger than what its using now. Hope this helps
