Sun tach troubleshooting

[JRSully]

Self contained (no transmitter req.) model 802. Hooked it up (checked to see I did it correctly), fired the motor, it won't read RPM at all, then it will bounce to the correct RPM, hold for a second or two, go dead again and then bounce all over.? Any advice here.? Thx
