88 Fourtrax electric start not working

New member here. I’ve been on the site plenty of times researching and it’s great. I have an 88 fourtrax 300 2wd. Hasn’t been run for years. Sort of a barn find. Anyway I have replaced all the fluids, filters and a brand new battery. When the key is turned on I get the oil and neutral light but nothing when I push the electric start. The headlights will not work either. It won’t fire when kicked also so might be an issue with the kill switch. Not sure where to start from there. Any suggestions? Thanks in advance.
