starter button delay

[madmaxx]

Hi everyone,

Sometimes when I go to start my engine I have to hold down the starter button for about 4 seconds before the starter engages other times it is immediate. I watch the voltage gauage and no dip happens before the starter turns. Do you guys think it is the button or relay, or has anyone else experienced this. Once the starter engages the engine starts imeadiately. I guess it could be the starter solenoid but once again I see no drop in voltage and when I do the engine starts.

Thanks
