this is a problem with the Joystick or a connection to the joystick. Check the wiring first. It has been my experience that the controller may also have a hand in this code. Have a Qualified tech check it out. Strege Mobility
If the chair does not turn on at all after charging and the batteries are over 18 months old, have the batteries removed and tested at a wholesale battery shop or specialty battery retailer (NOT Walmart. NOT autoparts!) Chances are the batteries are bad. If batteries load test fine then you have a wiring or controller issue.
The problem you are describing happens quite often and there are several solutions.
1. The manufacturer sometimes supplies a manual crank that fits in the end of the motor to manually turn the motor and lower the bed. This crank is usually lost or misplaced (look for it on the bed frame). With the weight of the mattress and person off of the head you may be able to use a pair of pliers or other tool to carefully turn the motor shaft.
2. There is a bolt and nut at the end of the head motor shaft or a hitch pin and bolt. Remove this bolt at the end of the motor shaft where it attaches to the head frame and the head frame will drop to level.
3. Fixing the hand control usually involves taking the two halves apart and bypassing the push-button switch by shorting across the head down switch. This is the best way to diagnose a bad hand control. This is the most difficult solution for the average end user. You ultimately will purchase a new hand control anyway so this may be a viable solution. The hand control gets the most use and abuse and is usually the faulty part.
You may have a bad relay on the junction box control board where all the motors and hand control are plugged in. If the motor runs in one direction, the motor is OK. If you have the micro-switch style 6 button switch hand control you may be able to clean the switches by spraying contact cleaner is the switches and pushing them several times. Check the hand control plug for bent or bad pins at the control board junction box. The hand control pendant runs about $100 and the junction box controller is about $400. Hope this helps.
The controller for this power wheelchair is a VSI controller made by Penny and Giles. The Everest and Jennings Metro Power III is distributed by Graham Field Health Products. The controller part number is #90762330.
To figure out what the flash code means go to the following website link for Penny and Giles(pgdt): http://www.pgdt.com/scenter/diagnostics/diagvsi.html
This VSI service center color diagram is very useful. It will tell you the problem with the power chair. A service technician will have a PP1 hand held programmer that will give more detailed information, but this is a start. Check all your wiring connections/plugs and make sure your chair is fully charged. Hope this helps.
The 9 flash error code indicates a communications fault. The communication fault relates to the communication between the joystick and the control module. The joystick on the arm mount is connected to the control module in the base. When there is a break in the wiring of this wiring harness, also called a bus cable, a fault occurs. This trips the computer and the computer sends out a flash code to the joystick. Simply stated there is a broken or pinched wire between the joystick and controller. Look physically at the wire and check for cuts, breaks or pinches. The best short term repair is to repair the broken wire with solder and heat shrink or tape. You can also use **** splice connectors and tape. The best long term repair is to replace the harness with a part available from Invacare. The most definitive way to diagnose this problem is to read the fault log of the controller using a hand held programmer available to dealers and certified technicians. The number and type of fault codes logged in the controller is another indicator of which
component(s) has failed. Hope this helps.
The 7.5 Amp ATO fuse is located in line with a rubber cap on it under the rear electronics cover. It is a well kept secret, well hidden, and you have to know its there. The rear electronics cover has an AC receptacle, meter, circuit breaker reset button, and main hand control connector on it. Remove the cover and look for the in-line fuse. It is a black rubber fuse holder with a rubber cover. It is connected with one wire to the harness connected to the charger and the other wire from it goes to the charging meter (red and green with moving pointer). It is probably easiest to find the fuse holder by starting at the meter and tracing the wire back to the fuse holder. Pull off the rubber cap and insert a new automotive style 7.5 amp fuse. You can tell if the old fuse is burnt out by holding it up to the light. If the wire inside is burnt open, the fuse is bad. Be careful when putting everything back together that you don't pinch or disconnect any wiring. Hope this helps.
Wolf you can contact a local provider that sells powerchairs and ask them to get you one. You can get an off-board charger cheaper than the on-board thats on the Jet7. I would check around your neighborhood for someone who might have a chair and have an extra charger or has an old chair that isn't being used and has the charger for it. Also check at a pawn shop for one Hope this helps you
